Depression with pregnancy

Is depression common with pregnancy in the second trimester. I’m just about 20 weeks and I can’t get out of this slump. I know it’s related to work because I hate my job. I cry when I got to bed because my anxiety is so high about going to work in the morning. I snooze my alarm until it’s pretty much time to clock in (I work from home). My work is showing my lack of effort. I cry almost every day at work because I hate my job and it is VERY stressful. Then when I’m done for the day I lay on the couch or just go straight to bed. My house is a wreck because I can’t bring myself to get up and do anything. I hate to admit it but I don’t shower enough because I can’t get my ass out of bed in time to shower before work and by the time I’m done work I don’t want to do anything. I’ve never had depression, just anxiety and stress. I guess this is depression. I don’t even know. Its to the point were I don’t even like weekends anymore bc all I think about is not wanting to go back to work Monday. Not a normal “everybody hates mondays” but it’s more like my heart starts racing and I get sick over it. My poor husband tries to talk to me about it and do whatever he can and I just cry. We went to bed around 9 last night and I couldn’t fall asleep just because I couldn’t stop thinking about how much I didn’t want to do my job tomorrow. And it’s not the fact that I’m lazy and don’t want to work. I love to work. I would quite and go back to my high school job at McDonald’s if I could stand for that long. But I can’t. And I can’t afford to loss my health insurance and other benefits, like short term disability for my maternity leave. I don’t know what to do. I’m afraid all the stress on me is effecting the baby. I’ve already had some complications with bleeding and a low placenta. I know I’m not going back to this job after I have the baby. Does anyone have any advice or been in this situation? I have an appt with my OB/GYN Monday and I’m going to talk to her about. I hate feeling like this. I hate feeling like this was the worse time to get pregnant. And it kills me to think that I have a little bit of regret for getting pregnant when I did. I don’t want to regret anything about my baby.
