Third trimester blues...

Anyone have any advice on how to stay positive during the last weeks of pregnancy? I have 7 weeks left, and I’m miserable both physically and mentally. I’m still attending classes and work, but I HATE every bit of it. If I could just relax, I would feel better, but that’s not an option. We can’t afford for me not to work yet, and I’m starting nursing school this fall, so I have to keep pushing. On top of constant anxiety, it’s all getting to be too much. I hate my current state of mind. I’m usually so positive and motivated...help 😣😢
