Stressed out

I’m not sure what’s going on but I’ve been so stressed lately and idk if that’s the cause for my lasting period (3 weeks), I go to school, i work straight after, then after work (which is usually 9:30-10pm) I do homework and I stay up until 1-3 in the morning trying to complete all assignments.

I’m stressing out so badly that my anxiety is coming back, I keep having break downs! My eating habits are horrible these days. And I just feel so drained...

Can I get any advice to help me out coping with the stress. I need it. Please
