35 weeks and feeling depressed :( is this normal?

I know I should be happy right now bc I’m having a baby, but I’m feeling really depressed. I hate the way I look I feel so large and I don’t want to do anything social anymore. I used to be really athletic and now I’m like out of breath from walking down the street bc my belly is so huge. I got approval from my boss to work from home, so I work from home in my pajamas and watch tv when I’m done with work and then just go to bed. I have no motivation to do anything else. I don’t even like people to come over to my house. It makes me jealous that my husband still goes out all the time and has fun with his friends. I’m worried he talks to other women and isn’t attracted to me anymore bc he seems to always want to go out and not spend time with me anymore. He said he doesn’t want to be around me all the time bc I’m boring :(

None of my friends are pregnant and my family and siblings live in different states. I feel so lonely and insecure and just sad a lot. Is this normal to feel like this during pregnancy? I’m not sure if I should see a therapist or not but I just wish I was happier right now 😢
