If I understand correctly, you trained in the Carib at one of the "lower tier" schools (hence the inability to be a resident in Cali), were accepted into two residencies. The first required that you repeat the intern year, and then subsequently closed. You were accpeted into a second, and was fired. All of this was in FM. You are now 2 years beyond that without having found additional training.
If that's the gist:
1. You are now at least 4 years post graduation (2 years of training + 2 years in limbo). It's "do or die" time. If you don't get your medical career resusitated at this point, it's only going to become more difficult in the future.
2. As a generic PD, I have no interest in simply giving you "another chance". You've had two chances already and not done well. In order for anyone to consider giving you another chance, they would want you to prove, as best able, that you had learned from your past problems and come up with a solution to improve. The details of such a plan are impossible to tell you without knowing the problem, and I completely respect that you might not want to post all the gory details here. But, it might include switching fields if there was another field that fit your skills better, or new ways of studying, or could include new skills you have picked up in the last two years, etc.
3. What new fields would be reasonable? Psych, PM&R, and Path are the fields that are on the low end of the competition scale and stress different skills than FM.
4. There is no easy way forward for you. I could totally understand how no PD would be willing to take a risk on you again given your history. Hence, if you really want to make this happen you'll need to really "work the system". You'll could work at / volunteer at a hospital with a training program and get to know residents and the PD, go to conferences, do research, network, etc. This is what it will take.
5. What have you been doing the last two years? If the answer is "nothing helpful to get me a new residency" then you have probably brought your medical career to an end, but if you get started now there is a small chance of success.
