Feeling really crappy. Im just over 10weeks don't know what to do?

For sum reason this pregnancy has me totally depressed. .... baby was planned n we were thrilled esp after a prior miscarriage. My husband shows me no love nor affection. It feels like this pregnancy has ruined my marriage. We dnt even talk anymore. He has now taken an interest in the way he looks and smells ect n it makes me feel like shit....because i look like crap now. N i dunno if he has as interest in someone else, because we haven't had sex or touched or kissed in 3 weeks. I cant eat, well im barely eating. Im constantly down n crying. I just dnt know what to do. I was a single parent to my other 2 kids prior to this marriage. I cant raise 3 on my own. Not again.
