I don't think most of us are having trouble grasping what OP is feeling.
Its more so that if you step back and think about it, the time table just doesn't make much sense. It would be one thing if it was a hesitant incoming med student feeling this way, but OP has gotten through clinicals and passed STEP 1 already. They only have two years of "school" left which is how long AA school is anyway. The alternative to "sticking it out" is not really much shorter or easier in this case.
Also regarding "true feelings and beliefs", its not like OP has suddenly found a deep passion for law or accounting or something. OP's choice of "out" is a field very adjacent to the pre-med-->med student pipeline. I don't believe these feelings are OP's passion or spiritual truth. I think its the burn-out talking.
Like
@operaman said, if OP drops out today and starts applying to AA school and gets in on his first try, then OP will become an AA at the same time he/she would have been a 2nd year anesthesia resident. And there is a lot of overlap between being a practicing AA and an anesthesia resident.
Are those 2 extra years of residency at lower pay than an AA not worth the 3x money + more career opportunities + much more geographic flexibility for the rest of your working life ?
In my opinion, the stress and burn out is preventing OP from being able to think straight and potentially make a decision they will regret for years down the line.
There will be no lack studying and bull**** to endure in AA school, OP. It's just how the system is designed in a broad sense not exclusive to med school.
I'd say 75% of young doctors I know were also jaded and less than enthusiastic by the 2nd half of third year, so you're just ahead of the curve. The good news is that with interests like anesthesia and psych, you wont even have to go out of your way to grovel for research or kiss @ss. If you just push through and do your time it will pay off, all of those former jaded med students(now doctors) I know are glad they stuck it out.
