so im 18 years old and think i might possibly have adhd but im not really sure... im always irritable like even the slightest things will %#@&#! me off and it gets really bad. I'll snap out at people for like no reasons even when their trying to be nice to me. I'm not really very hyperactive but i'm constantly shaking my leg to the point where people ask me to stop. I never really noticed it during school but now that i think back i had good grades in the classes which really didnt count homework. I never ever would do my homework... i'd either completely forget or just couldnt concentrate enough to do it. Now at work I notice some of the symptoms like my asst. manager will always say she has to babysit me because i'll wander off from doing something and start talking to someone or doing something else. She constantly has to remind me to do my daily chores at work like take out the trash, do my returns, clean the windows.. etc. It really hit me when my register at work was $40 short. I've never been short but it seems like i've been making more and more careless mistakes. It takes like hours for me to fall asleep and than i can never wake up in the morning when i need too. I constantly have a zillion thoughts running through my mind and im always anxious. My self esteem is pretty low and ive realized that every relationship im in ends in me being told im immature even though i don't see myself as immature. I tend to overreact in situations and it's really frustrating. The only reason im not 100% sure i have adhd is because i really don't remember it as a kid. But I think the worse part of it for me is the irritability and my short temper.
