$3K a months is ok, IMHO, in FL for a single person without great medical needs. Not a luxury living but ok. Anywhere in the former USSR, that's a luxurious living for sure, except maybe Moscow and St. Petersburg, maybe Kiev too - but it's quite fine for those cities as well.
There is a ton of building going on in FL in anticipation of baby boomers retiring. I think the job market will be very good here. Right now it's mostly in construction but soon all kinds of professions will be needed, first and foremost medical. If your particular job's too stressful, you could consider looking for a related job, etc. if you have to.
Albeit, I vote you stay there where you are... (you asked...)
