Still stressed out about my culinary pastry final and my culinary knife skills the following week

Lately I've been crying in my apartment and getting unnecessarily stressed about my pastry final and my culinary knife skills test. Last week I got my period on the weekend (I normally do my studying then) so I wasn't able to study like I wanted to but now I'm really stressed with all the stuff I'm thinking about. I tried hanging out with my ldr bf but all I could think about was my test I never felt this stressed in my life and I just want to relax and not be so tense about it.

I tried doing sleep sounds to relax to try and sleep, and it works for  awhile until I get stressed at night again. It's not like I'm failing my classes, but I really want to do well, even as I find strategies to tackle both tests I think about my assignments including a midterm I have on Friday and I just get so stressed out with everything. 

I tried talking to friends but nothing seems to be working and I just don't know what to do, I know my stress is irrational and I should just relax but sometimes I have dreams about failing and not doing well. 

This week I'm going to a Korean festival happening at this church figured it would just help me get out of my apartment but other than that I don't know what to do. I never gotten this stressed out before and usually if I distract myself it helps but right now distractions aren't helping

If anybody can give me tips or advice or words of encouragement that would be great
