Toxic jobs really take a toll on your health, especially if you feel trapped in them. Looking for a new job is really a full time job on itself, it can be hard to do so while already working a full time job. If you feel your job is toxic you should start looking for something new right away - whether you've given notice or not. I've ended up in the hospital twice from the toll toxic jobs that I felt trapped in took on me. Another thing you can consider is diversifying your income. Ie, a "side hustle". If you have more than one income stream you won't be quite as trapped. You also will have something to help buffer the transition between your real jobs.
