loneliness and depression

I'm 26. Lately I've been terribly depressed and lonely. A month ago my bf and I broke up. We had been together for 5 months. I still love him so much. The day after we broke up, my cousin passed alway. I've been feeling very alone. I am also so tired of my job. It's become a dead end job that I absolutely hate. I've been applying to other places daily and been rejected. Idk what to do anymore. I went to a good 4 year private university and I make almost nothing. I even paid a resume service to help me out with my resume and cover letters and I can't get any of the jobs I want. I get out of work with no energy to do anything except lie down And browse the web. I have very few friends. The ones I do have I don't see too often, bc they're busy or our schedules conflict. I feel like my life has amounted to nothing. Idk what to do anymore. I just wanna cry.
