Hi, and thaks for taking your time to read this, actually this is the secont time I have to write this because I accidentally ended up publishing when I was writing, so I delated it and started over again.
I am a 16 years old boy from Argentina, and I think I may have ADHD.
I've been suspecting this for some time now, since I watched a video of a youtuber that has been diagnosticated ADHD, the video wasn't exactly about ADHD, but at some point he mentions about how he was diagnoticated and some of the symptoms (If I say something wrong please correct me, english is not my mother language, so I always apreciate corrections) of ADHD. 
After I saw that video, most of the things he said about the symotoms stucked in my head, and I started to compare it to many things that hapened In my childhood and things that happen me now. Things like hyper focusing on things, mostly things of my interest, strugle at social encounters, leaving things incompleated, making almost contant info domping on people, daydreaming most of the day, in school and in my home and how my dad and mom (divorced) always neaded to supervice and help me at compleating schoolwork, homework and study for exams, at least until my last year of primary school (here is until 12 years old). Since then people expect me tobe able to do those things on my own, which I should, but I've always strugled. In my frist year on middle school I barely passed with 2 disaproved signatures (they let you have a limit of 2 signatures disaproved, but  you have to aprove them the next year, and you can still disapove them unless you acumulate more the next year, if you have more than 2 acumulated at the end of the exam instances, you have to repeat the year) and that with the help of my mom at the last second, but I wasn't so lucky on my second year, and I repeated the year in other school (I wasn't really happy at my other school) last year was my repetition of my second year of middle school, when the pandemy came and made all of us stay at home all year, and again, I barely aproved because of my mom and she helping me to complete most of the things, this time without any signature to take this year.
But now I'm expected to do all on my own when all of my life I've been used to be helped by an emocionally abusive helicopter (my mom) always behind me. Now is time to talk about my relationship with my parents, because it's not all pink and rainbows everywhere as it may sound because of how much she helps me with school.
My relationship with my parents it's very complicated, when they divorced, I always ended up seeing them fight, thoug most of those memories are a bit blurry because I only had 5 years old when they divorced, but I remember well seeing them fighting and arguing all of my life. I know that at some point my dad denounced my mom saying that she was psicologicaly abusive to me and a lot of other bunch of things that I don't really remember, aperenty I expresed desire to stay whit my mom so it ended there. It's important to say that I principally lived with my mom, and visited my dad the weekends.
I always strugled in school, not only academically, but socially to. I tried to make friends, but bullying was always a thing.
I had a friend, which I ended having a crush on on my last years in primary school, but he made a friend that liked to bully me and he started bullying me to, but I still saw him as a friend, actually, I realised of my crush after 3 years that he started bullying me, on my last year, discovering my homosexuality, which wasn't the best moment, because it was a really toxic relationship.
After that I entered in middle school in another college, but it didn't go well, a lot of crushes, a lot of broken hearts, the stress of school and a friend that accidentally filtered my homosexuality to the whole school when I was still exploring it and figuring it out, making me the perfect target of bullys and people to treat me diferent because of that. I really suffered a lot becuase of all of this, I asked my parents to change me to other school, but they didn't agree, and said that it was a good school and that they liked it, because it was a technical school (which means that they have extra signatures and that you have a specialisation, which gives you a title and with that you can work after you end school. It also means that this school has an extra year). I really did't like their decision, so I told them that if they didn't changed me of school, the next year I would repeat on purpose, they obviusly didn't take it seriusly, but soon they regreted that decision. I really didn't have anything to lose, considering the extra year of that school, so I repeated the next year.
I already told you about last year, but I haven't told you about the school I'm in. I really like it here, I have some friends, everyone is fine with my sexual preferences, no bullying, but again, a lot of emocional strugle. The pandemy combined with all my past experiences and my resentment to my parents because they doing nothing about the bullying and my strugle in my last school was a big and fat bomb about to explode.
I almost forgot to tell why I think my mom I psicologicaly abusive. She always was very explosive, cold and manipulative, especially when she can't control things or people, my freedom and privacy (both things normal at my age here where I live) are in constant threath to be taken away from me. She was like this most of my life, but it's worse now because she has some health problems relationated with her ability to go to the toilete, nothing life threathening but she still struggles sometimes.
Sometimes I have to hear she yealling at me out of making a simple question about where something is. And on the top of all of that is the fact that no matter what she may have said to you, if she was furius, yelling at you, saying that you are a disgrace or that her life was worse since she had me, after an hour or two she treats you like nothing hapened, like she said nothing about that to you and she treats you always gentle and smilie. It's almost like talking to two totally diferent persons. I would lie If I said that I ok with this, and it's been more than one time that she had almost drive me to crazy mode and me wanting to just brake something in her head while she yells at me.
And you may ask "And your dad?", well, right now he lives with his wife and my 3 years old lil brother, and I haven't stayed in his house since the pandemy started, in part because I had an argument with his wife, which we finally talked about with her this sunday, also with all the other things that I suffer in my grama's house (I forgot to tell that we live here since 2018, when my grandfather died), but now they don't really have space to me to stay in, beacause my brother sleeps where my room was before, thing that I have no problem with, but means that I have to stay here, which I really don't like.
They would need to sell the house where I lived before to be able to buy something more big and let me start visiting them again, but I want to get out of here right now, and my mom won't agree to sell the house.
Now, the big problem and the main reason I'm posting this (sorry for telling the story of my whole lofe, but it was necesary for context), I disaproved at least 5 signatures, and my mom doesn't know, I don't really tell she my problems due to our problems and her way of reacting to things, but the school gives the parents our notes the 4 of December (the last day of school), and she will definitly punish me and yell me a lot when she finds out, and I'm really afraid of how she will react, I've been strugling with my feelings and school alone since the year started, and it's hard that the first assumption of people when they see my grades and how little atencion I pay is that I'm just lazy. I don't really know what to do now, and I don't want to summon the fury of my mom, but my dad (who knows about my grades) can't really do anything right now, but I need a solution quick.
Last things, my dad and mom imediatly discarded ADHD when I proposed that, but my dad's wife took it a lot more seriusly, and my mom said that if I disaprove more that 3 she is going to take my phone and give me hers. Mine was a gift from my mothers part granny and my dad payed the half of it. She also says things like that my dad has to go out to eat launch with me two days a week because "It's not buisness" other way.
I'm also starting therapy with a psicologist, but is just been 3 sessions and it's online.
