38 weeks and depressed

I feel like this is more of a rant but I'm kind of looking for advice too. I absolutely hate my body. My whole life I've been in good shape and felt pretty because of the way my body looked and now I feel like it's ruined. I know I signed up for pregnancy when me and my husband were trying but I didn't know this would be hard, accepting that my body has changed for her. For example, my back goes straight to my ass now and my ass is literally huge and covered in stretch marks. Same with my legs, covered with stretch marks and have grown in size and I've lost all muscle in my arms and now it's flab. I'm used to having this awesome metabolism so I never worked out before pregnancy. Now I just don't know how to handle this sadness I have because let's be honest, a lot of girls are concerned about their body. I am one of them. It makes me so disgusted when I get hungry time after time.. I hate it so much. Two questions: Is it normal to be this sad about my body? And will things go back to the way they were after post partum workouts?
