I had the same problem. My depression had been latent since early HS but it really manifested when I began college, and my grades were horrible as a result despite having been a model student until then(well, until the last year of HS; college only hastened its development). I'm 29 and I've since gotten treatment but the effect on my professional development has been incredibly damaging. It's less a stumble out of the gate than a foot shot.

I know intellectually that I've achieved as much - or possibly more - than my typical peer because I've worked through my problems and traumas and come out the other end alive and healthy, but they're still the ones with the comparatively advanced careers, living in nicer cities, and taking care of their young families while I'm still working saw jobs in the midwest and living, alone, in a studio apartment.

But I'm alive, and I'm able to finally live a normal life, which is priceless.
