So I’ve been an A star student my entire life but when I entered college, I figured out that I daydream a lot in lectures and online classes especially when the teacher’s way of explanation is boring and can’t concentrate on a single word. My way of studying also changed that I have to say things out loud in order to memorize things unlike in school, I used to write the lessons several times to memorize them. I also get distracted easily either at school or at the house. I used to be so quite at school receiving praise from all the teachers but now I feel like I want to do anything except listening to lectures and I want my classmates to play anything with me but I feel that they are all really boring. I sigh a lot when I want the lecture to end. I can’t wait for the exams to start in the exam hall. I just cannot believe I passed the first semester because that A star student became less than average. So I searched about my condition and I found out it could be ADD because of how easily distracted I’m but I can also relate to ADHD due to the fact that when I checked the symptoms I found out that I relate to some of them:
I overshare (which I struggle with everyday, counting the number of times I open up with people)
I have craving for certain things like certain types of yoghurt which motivate me before I study and I really chase motivation 
My room is messy
I forget people’s names
I avoid eyecontacts
I interrupt people and switch topics where I can say different topics and forget about the first topic 
I no longer make schedules for my studyings because I always end up procrastinating due to the excessive daydreams and I always try to fit many tasks but I fail to finish them all. (Sometimes I only finish a single task out of 6 tasks)
I can study one day very effectively and then the other day I just don’t want to study and I don’t know the reason 
And other symptoms of course, but how could I have ADHD when most of these symptoms just appeared this year? How could someone develop a disorder after a certain age? Is that even possible?
Note: This year has been the toughest one ever because of many unpleasant events that happened in my life 
Do I have ADHD? My parents are still not hundred percent convinced because it just happened this year.
