Is this depression?

I’m currently 9 weeks pregnant. Haven’t been able to get anything down my system for a week, I’ve been arguing with my husband all the time & I feel alone. I’ve been envying lots of families because they actually go out to eat or do fun activities with each other... I’m always at home, I try to invite my friends out to do something & they all bail. I feel like I’m not being a good enough mother to my, soon to be a year old, son because I’m always feeling down and have terrible pregnancy symptoms. I’m happy and then my husband brings my mood down. I used to be a happy girl & outgoing! Now my life has turned upside down, I don’t recognize myself. I just keep thinking to myself that my husband deserves someone better because he’s always pointing out my flaws... I do commit lots of errors but I’ve been loyal and have been trying to put in my part but he doesn’t get how it is to be pregnant. I just feel isolated, with nobody to talk to w/o judging, nobody to hangout, or have girl time with anybody... my friends stopped talking to me because they don’t like the way my husband is with me & just decided to eliminate me from their lives. Once again, I feel lonely... with no hope to strengthen my relationship or be a better person... the worse part is girls my age are living their lives while I feel like I’m caged in... I’m only 19.
