I've let nerves get the best of me on more than one occasion causing me to have to repeat classes a few times. I've gone to a doc to get medication just to complete things or classes. I'm really unsure how the stress of med school would/will undo, what lack of present stress has helped to heal. Unfortunately in order to get to heaven, I guess, you got to go through hell. Though I'm worried I'll spend a ton on tuition only to fail classes at a higher level, come apart and end up with a huge debt and no degree nor classes to be able to show for it (there's only so much you can borrow or ever hope to payback even with a med degree). And then after all this tragedy, have to reapply to a different career path and still have loans to payback from the failed attempts. I've seen more than one peer go this rough stuff and it ain't pretty. I was always told be careful for what you wish, you may just get it and then what...
I'm just trying to think it through and be realistic about the time, effort and committment required to do this and see it through for a lifetime career and indebtedness.
