I had same feeling, but after rethinking the whole thing, I concluded that it was my hormone that makes me want to quit my job. So I tried to think abt the long term consequences. Comparing toxic working environment and uncertainty of my hubby becoming jobless during this covid era makes me stick to my job. At least if one of us lost our job, we still have backup. Do take care of your mental health, try to do more fun activity during your free time to release stress. All the best!
