Dealing with depression while pregnant😔

I have been having major depression problems lately and I'm 37w pregnant with my first.. I feel horrible because this is a time when I should be super happy and excited. I'm scared the depression will get worse or won't go away even after I have my baby. I don't want to be unhappy like this but with our current situation its hard not to be depressed.

Husband and I have to travel to make a living. Sounds nice but we sacrifice so much for this stupid job. We have to live in a camper. We are never in a town long enough to feel comfortable and at home in it. We can never make friends because we are always on the go. We are never close to family. Where we are from there just isn't any work, so we have no choice but to do this. My dream is to be in a real house on some land or neighborhood, near family. What is so normal to have for everyone else would take a miracle for us to have. It feels so unfair. I need my family. I need their support. Other than my husband, I have no one I can rely on. These are suppose to be the best years of my life and I don't even get to share them with family. I'm by myself 99% of the time since my husband works 6-7 days a week.

I do my best to smile and laugh for my husband but at the end of the day when he is asleep and I'm wide awake, it all hits me. I'm really struggling mentally
