How to deal with failure

Hello.

I was diagnosed with a debilitating mental illness (schizoaffective disorder- pretty much a combo of schizophrenia and bipolar disorder) after freshman year of college, losing and alienating friends and killing my social life. I was put on meds and I was functioning pretty poorly (speech and socializing sucked and motivation to work disappeared). I went off meds and as within a couple of weeks, I improved rapidly to the point where I was able to land an internship at a Bulge Bracket in Global Markets.

However, I didn't know that my elevated state was a sign of mania. This lack of meds destroyed me. This mania became worse and turned into full psychosis, again ruining relationships and resulting in me having to leave school and cancel my internship. I've recovered and am currently on meds, with no plans to reduce or stop taking them.

Now I'm in my final year of college, with no experience (the internship is on my resume as a boost) and it seems like I have no hope of landing a decent job. I am very concerned with my future and building a stable career, especially with my mental illness. What do I do?
