I need advice, or help

I didn't know where to post this. My son is 19 months. And this is my second pregnancy 7 weeks tomorrow. iv always had a rough time with anxiety and Depression. But manageable. after my son was born. I had post partum pretty badly. I felt like a horrible mother who couldn't do anything right. well. I have been very very hormonal this pregnancy. But it's so much deeper. I have a great husband a pregnancy we were trying hard for. but I'm so depressed. I feel unattractive, like a failure like nothing's okay. I want to change our living situation but can't right now. I have been on my husband for weeks now everytime a girl gives him attention yelling and crying.. But he loves me and would never hurt me or cheat. But I'm really struggling. is this just a hormones thing... or bigger? I can't stand it anymore
