Pre-partum depression?

I don’t know if that’s a thing but I have just been really upset lately. I am almost 35 weeks and I feel tired and hurt all the time but I’m nesting like crazy so constantly cleaning. Plus still working 40 hours a a week. I’m emotionally exhausted. Plus I’m feeling just horrible about my body. I’ve gained a lot of weight (almost 40 pounds) and my husband hasn’t wanted sex for the entire pregnancy. Even blow jobs. He’s just stressed and not interested. It makes me feel so bad about myself and just horribly unattractive. We have a good relationship otherwise but I’m starting to get really bitter and resentful towards him for not making me feel better about my body and having holidays off while I work my butt off 35 weeks pregnant (I’m a nurse)
