Stuck in my head

The only days that i don't feel stressed is when i'm with Rylie. But sometimes it seems i sometimes get stuck in my head. I'm constantly fidgeting with things and my leg is always bouncing. I still think i have asthma because having to go up to the second floor every day all week causes me to have trouble breathing and it's so difficult to get it under control. I've had 2 incidents like that today and i don't know if it's actually asthma but i think it is. Sometimes it gets so bad that i have to drink all of my water just to be able to catch my breath. Sometimes i zone out everyday, all day and i don't ever actually know why. And sometimes i lose my emotions. I don't know why but they just disappear. It happens when i'm at home, at school and in public areas. I get scared easily and people ask why but all i can say is "I don't know". People are always asking if i'm okay when this happens but i don't really know that either. My mom and sister make it worse but there's nothing i can do about it. Someone please give me some advice and info on the asthma situation.
