Firstly I apologize for my english which, I suppose, is not perfect at all. I'm french so english isn't my mother tongue lmao
I'm and I've always been a very stressed person.
But since a couple of months, my life has been a fcking mess with Covid and everything else that's going on in my personal life. I'm in 3d year of what we call licence here in France so I'm at college. But at the same time I'm working at Dominos pizza 25h/week. At first I handled it but now with the exams coming I'm really struggling. I feel like that amount of things to do is never going to end. I have an exam tomorrow and I'm working to midnight tonight. My nerves are about to break. My head is a mess, my sleep is a mess and my face is a mess too. I can barely recognize myself sometimes.

I am trying breathing exercice to help my anxiety but I wonder if you have extra tips to help.
Thanks for your help..
