Should I quit my job?

I'm stuck in a very stressful and unhappy situation. I'm pregnant and very unhappy at my job, on top of that I have two kids from a previous marriage. I'm currently with the guy that I'm pregnant by but I have to work, he wouldn't be able to support us. I've never had to work through a pregnancy before. It's stressing me out. I'm currently 5 months pregnant and I think I should be resting more often than not. I'm stressed out working a job I hate, also being a mom, cleaning, and having to keep up with doctors appoitments which I've had to miss some due too scheduling conflicts. I'm also not happy in my relationship but I'm doing my best to make it work. I'm so unhappy, stressed and depressed. Nothing about my life inspires me. Should I quit my job and tell my boyfriend I got fired? In hopes that I'll find a better job I'm happier at? I already call off work so much and he doesn't know it. I just don't know what to do anymore, I'm so unhappy about so much. I can't afford counseling.
