Hi, I really need some advice.

Every cell in my body is drained. Im currently in my first year of uni and the exams are next week. I feel like no matter how hard I try, I cant get that stuff into my head. Its so much and I think I will fail in at least 1 or 2 exams. This puts me under so much stress. Next thing is, my bf and I have lived together for almost 9 months now and we're going to move into a new apartment in 2 months. 
I should be so happy but I live in constant stress and anxiety. Im afraid that something happens, that will ruin everything for us (for example losing a job or getting kicked out of uni - which is all very irrational). The stress of organizing and planning the move comes on top.
I dont know what to do anymore, no matter what I try, I cant calm down and of course it starts to annoy my bf too, although he understands. I feel like having a panick attack 24/7 and I am so exhausted. I wanna run away from everything. I wanna vanish. Its too much and it wont stop.

PS: I was in therapy for years and I am currently looking for a new psychologist...without any luck:/
