Tips for studying when depressed?

I’m a college student and I’m trying my best to get all As this semester. I have worked my butt off to get As on all my first tests. But now my classes are getting harder and along with that, I’m becoming extremely depressed every day. Every time I study, I feel so depressed and lonely. I need to study though, but I physically can’t because it hurts so much. It’s like trying to study with terrible period cramps. Does anyone else deal with depression and have tips to study?
