I think it depends on how much of it is the job vs. how much of it is health. I change jobs ALOT I'm 34 and I've had about 40 jobs in my life but I think it's more to do with me not handling life too well and less about the actual job. I feel like the majority of work environments are toxic these days it's become fairly normal for everyone to be mean to each other but I'm extremely sensitive so it's harder to put up with.
In my case, I think it's mostly evasion when I leave jobs but that doesn't mean you should stay in a very toxic workplace I just think all places feel toxic it's just like what level of toxic/ stress do you feel is okay to deal with. Hope that makes sense my words are weird today.
