depressed at 6 weeks

Hello. has anyone else gone through this. I am currently 6 weeks and am feeling very down. It's my birthday today and I just decided to go to work, and not even tell anyone it's my b-day. I don't really like anyone right now, i am in a bad mood and don't really even like my husband, everything he does bothers me. my first few weeks I was fine, this all started during my 5th week. will this go away?
