Depressed

I've been feeling really depressed and inadequate lately. My husband won't look at me, let alone touch me. He hasn't kissed me, or said he loves me in two weeks. When we speak it's because he wants something or we are arguing because he is frivolous with money. 
I'm still not completely through this miscarriage yet. My hcg levels are plateauing instead of dropping to zero and I'm going through this 100% alone. 
People at work won't stop giving me looks, and they avoid eye contact and coversation. I've never felt so alone in life while surrounded by so many people.
At this point I'm not sure that my life has a next step. This is my second miscarriage and I'm not sure I can handle a third. I've contemplated ways of ending it in my head, carefully analyzing each situation. 
I really tried to talk to someone about it and he just wanted to talk about himself. I'm too nice of a person. What did I do in a past life to deserve all of this?
