Handling depression at work

Let me start out by saying I'm a nurse, since the pandemic started my depression came back. I started back on an anti-depressant in August of 2019, upped my dose in October, and up until around March I was doing fine. Then here comes COVID 19. I think I was okay until the first night I worked on a COVID unit. That next day, when I was off, here comes my symptoms of depression. I hadn't spoke to my therapist since the beginning of February because I didn't feel I needed too, she even texted me to check on me. I didn't seek out the help of my therapist until the end of June. By this time I wasn't working on a COVID unit anymore. I am more stressed than ever because I've had to work overtime since March, it was just every other week. But for the past to weeks we've been made to work overtime every week. This has been a real problem for me. I feel like I can't relax at home, have trouble finding something to occupy my time including finding something to watch. I don't want to be at work but I also feel restless at home. I have changed to a different anti depressant and I'm two weeks into taking a starting dose. I am so tired of working extra and being asked to do more. I know the stress is making my symptoms worse, but what can I do? I like my job, but not being forced to work more that I ever usually would.
