I'm not diagnosed professionally. I think I have some form of it. I have a lot of the symptoms. No motivation to do anything, etc. These past few years of the pandemic really fucked me up. For a while I lost the motivation to do the things I used to love. Used to play tons of soccer. Was pretty damn good too if I do say so myself. Recently, starting high school, I haven't touched the sport. Havent for about a year and a half. Considered suicide sereously. Lots of times I debated whether or not to just end it all. For a bit of perspective, I used to excel in school. Straight As through elementary and middle school. Now, I can't pay attention. I don't wanna do my homework. I don't want to wake up in the morning. I try and explain to my parents about this, but I get the same reply. "it's just school" or "I don't wanna hear it". and I gave myself that mindset for a while. It's just school. Right? wrong. At least not for me. It is just a hell of zoning out, and frustration. I get shit test scores. I am constantly lost. I feel stupid . So many times when I genuinely feel insane. At my school, classes are 100 minutes. Pretty damn long. Some arent so bad. my history class is okay. Math is where I feel it the worst. I recently took a test and I knew I wasnt gonna do good. But when I got a fucking eleven percent i almost cried. There I was, holding back tears for more than an hour. learning things that I wont use. 
I almost convinced myself to commit that night. Thought I was gonna take a gun, go out into the woods for a walk and if I still wanted to do it I would look at the moon one last time and do it then.  I didn't do it. Personally, my life gets so much better on the weekends. I do things I care about that make me happy. Football, outdoors, animals. I love that stuff. Don't wanna be corny but it kinda keeps me alive. Then, the inevitable comes. School. I don't think theres anything i can do. I hope I don't wake up tomorrow.
Hope this applies to all the rules. Just needed to get it all out to some people who understand.
