How to survive if you can

I am in an abusive relationships for more than two years now. I experienced a lot of emotional and verbal abuse. Rarely physical, but even once is enough. The problem is, both of us are not US citizens, he is a student in grad school and I am not permitted to work with student spouse visa. Therefore I financially depend on him. I apply to the grad school this year, so hopefully I will have my own scholarship fairly soon. But it will be in six months or so and I need to survive with my abuser before that time. Does anyone have any advice on surviving in such circumstances? I just want to stay sain. I self-harmed myself after our fight with him few days ago because I cant copy with all this pain he is giving me. I am depressed and have no friends to talk to. I have no access to therapy or counseling. I dont want to give up on my career because of him being a jerk, but I am so depressed and tired. Please, help me.
