I enjoyed my last job, until I didn't. I decided to leave and live off my savings for a few months. It was the best decision I ever made for my mental health. More than a few months later, I'm still looking for a job, but with a better understanding of what I want in a job.
Now, do I actually think I'm going to find exactly what I'm looking for? Probably not lol. But whatever. I do know there is no reason to stay at a job you don't like, and every time I change jobs, I like to think I'm getting closer to one I can stand long-term.
Don't take my advice. I am a stranger on the internet.
