Last year I had panic attacks (don't know if I should say developed or got them) and now many months after talking with my psychologist I haven't had a big panic attack in months and I have done many things I wouldn't have even dreamt of doing last year.

This month is especially stressful for me, because I have 5 exams to take. When I took my first one this week, I barely slept or ate, but somehow managed to take the exam without feeling too anxious or panicking. After that I spent the rest of the day just laying or napping and it took me few days in total just to feel kinda normal again. My mom was waiting for me behind the school the entire time it took me to take it, so I felt much safer going there.

Last year when my dad dropped me off to my classes, I panicked the entire class and couldn't stay there much longer, so I called my mom and just left. Then I didn't know about my panic attacks and I did not attend another lesson. Virtual school happened anyways, but even when we had to come back in May, I just couldn't. I did not feel safe there on my own. 

Now the problem - next friday is my math exam. Math is one of the subjects, where I feel completely unprepared and scared about, but my mom won't be able to be there for me that day, she'll be working near, maybe 15min away, but she isn't able to leave that area anyway, so she will have to drop me off. I just don't want to be left alone, which sounds stupid, because there will be many people there. Thats stressfull too tho. And in general, it feel like she forgot I have panic attacks or feel anxious 90% of the time, she just sees me without it or my past self. 

How do I get rid of this fear? I have taken many tests before, I have spent many hours in other cities on my own, so why am I so afraid to take the exam on my own so bad?
