Feeling Lost and Seeking Hope

Assalamu alaikum, I'm a sister in med school far from home, and I'm struggling. I made istikhara before coming, but now I feel so out of place. Back home, I was regular with salah, but here, I've slipped and lost motivation. I'm failing exams, dealing with anemia and mild depression, and just want to give up. My parents don't understand-they've been harsh, and when I failed before, my father called me names. They've hurt me physically and verbally since childhood. I tried so hard, but after failing, I was stuck sleeping for months because my father wouldn't let me come home. I'm overwhelmed and don't know what to do. Please make dua for me. JazakAllah khair.
