Just be honest and straightfoward about your medical condition and try not to use it as an excuse. Just try to demonstrate that you have overcome obstacles. You are an MD PhD so you must have some smarts. You should be fine.
There are plenty of people who are far less qualifed academically than you and got in. Im not joking. One person on the reddit forum mentioned path is one of the top 4 least competitive residencies in medicine, which is unfortunate and sad for the field but it is what it is.
I see a bunch of these posts… “graduated 5-10 years ago, was a pediatric surgeon in my country, applied to internal medicine but didn’t match, am a medical assistant in a internal medicine private practice group, but I suddenly found my passion, Pathology. What are my chances?” LOL.
