About to be fired – is it a good thing or am I self-sabotaging?

I moved across the country for a job that has turned out to be a lot different than I had expected, and I have missed home a lot. In addition to that, I have had health issues that have been interfering with my work performance, and the combination of health issues and being unhappy in this job, I haven’t been able to show up the way I should.

I am trying to look after my health now but was told that I am on the verge of being terminated. My question is, is that a good thing for me? Or am I self-sabotaging myself somehow? I would like to move back home but there are financial and professional repercussions to losing my job right now. Also I am worried that my health issues won’t resolve and I will have these same issues in future.
