I'm sorry this is happening. Stress is a major issue for me with my bipolar. When I was in school I wasn't able to work and do a good job with school.
I think it's very important that you find ways to relax and decompress. You need to take care of yourself. Our world tends to run us over with all the high demand for money and success and independance. Finding time to just be you outside of that is extremely important. You need to take care of you.
I hope you start feeling better soon.
