Depression and suicidal. Mistake.

Hi, it's been 3 months now that I have this continues depression, I am sad most of the time and it takes lot of efforts for me to forget all negatives and be happy. Nothing seems pleasurable anymore. I have issues with my husband, we most of the time don't reconcile over any topic, end up fighting, there have been violence between us as well. I don't feel any love alike things anymore as I feel there is no respect left in our relationship. I have discussed this with him, but he says we will work out, but doesn't agrees to go and meet a doctor. I am really helpless and don't know what needs to be done, I get very bad dreams every night, don't feel like going to work and feel getting married was my biggest mistake.
