Do I end it?

I need some help, I've been unhappy in my relationship for the past year, but I love him so much, I don't know whether to end it, I don't see any light coming from ending it, I have no where to go, we live together, I wouldn't have a home, I also have major depressive disorder and I'm afraid I won't be able to cope without him, I don't want to break up but I'm not happy, what do I do?! Please help
