First of all, I'd say congrats for realizing what you DON'T want to do...that is a step down the road of deciding what you DO want to do. I think you were right to get out of anesthesiology b/c it doesn't sound like it was a good fit.
Finding a job for next year might be a little bit of a challenge, but I think your first priority should be to find a specialty you actually want to do. You could surely get an IM or family practice spot, if you were competitive for anesthesia, but don't do that just b/c you are desperate. I
M calls can be very long, up to 30 hours Q3 and Q4, sometimes for several months at a time, but how intense an IM residency is varies quite a bit, from what I have seen (I am an IM doc). Most of the bigger more well known academic IM residencies have intense intern years with a couple ICU months which can often be Q3...and will have ICU months in PGY 2 and PGY 3 as well. Some other less intense programs, like community or primary care ones, are less intense. The good side of IM is that once you are done with residency the career options are pretty flexible - hospitalist and primary care are going to remain in demand, and probably medical subspecialists as well.
I you like thinking/problem solving, and want a better lifestyle than IM offers, neurology might be a good option. The caveat is that the first couple of years of residency can be kind of intense - you have to do a medicine intern year plus then the first year of neuro is kind of like being an intern again (only in neuro). You have to do LP's, but otherwise they don't do a ton of procedures.
You could explore some of the lesser known fields of medicine (physical medicine/rehab, preventive medicine, pathology, etc.) which just tend to be lesser known b/c a lot of med students never do rotations in these areas. Medical genetics, too. All these have good hours, and I would think less stress than anesthesia or IM. Psych is also a great field right now, in the sense that it's easy to get a residency and psych docs are in great demand...also the residency (and attendings too) have good hours.
As a TY year intern, you're in a pretty good position now to perhaps try to make time to go talk to some faculty/dept. chairs at your current hospital. Just tell them you are considering their specialty area, and what do they think are the pros/cons, and you could show them your CV to see whether they think you'd be competitive to get a spot.
Again, you could definitely find yourself a spot in fp, IM, and probably peds, but don't just take a spot because you are desperate. You do need to move quickly (like make a decision in the next 2-3 months if you think you can) but don't just grab for anything.
Consider signing up for Findaresident on the NRMP web site. My best friend was on there for a while, and I think it only costs $35 or $70 for 1 year, and it was helpful for her to just see what was out there...you can search for open spots in pretty mcuh any specialty.
