Why is eye contact so hard?

ive had this problem with eye contact for over a year now and im 18. I never had it before i always made eye contact as a kid and later in life but ever since i had an anxiety attack i cant do it. Its way to intense of a feeling for me to hold it its like somethings pushing my eyes away i get sort of a buzz feeling in my head when i do it. I also think in my head how i look and the other person judging me to an extreme and it just feels uncomfortable. I read symptoms of aspergers and eye contact is the only thing i really fit into. I always had friends always got sarcasm jokes i have alot of empathy maybe too much and i used to be able to make eye contact but i cant anymore it litlery feels like an electric shock in my head lol idk any other way to describe it. I have ADD and OCD and im wondering if it could be anything to do with that.
