Hi, Katz224, and welcome to Psych Central! It's hard to say what all might be going on with you and your dad. Here are some thoughts. More than one of them might be true: 1) You do have some ADHD tendencies, so you get distracted, especially when you feel under pressure. Or just the pressure and anxiety could lead you to get mixed up; 2) Your dad is just feeling overwhelmed with caring for you and your mom and needs some "me" time away. 24/7 is a lot to deal with. Is there anyone who could come in to help out sometimes, even if they need to be paid helpers?; 3) Your dad is worried about how you would deal with school, especially if it involves a classroom, so he is sort of passive aggressive about the whole thing; 4) He takes out his frustrations on you because of what I have mentioned before.

Maybe you, your dad, and your mom need to try to talk about these matters. Okay? I hope things will go better soon.
