Wow I didnt expect this topic to get so popular given the initial response. Hayley, thank you for sharing your story - it is good to hear about someone overcoming a great adversary in their lives. I commend you.
I know how it is to grow up under bad circumstances. I thought I finally escaped my past when I graduated from engineering school. Only after did I fall into a pit of hell when I was diagnosed with bipolar disorder after I was hospitalized for 2 weeks. I basically lost every opportunity to I had to go through graduate school smoothly in the span of 2 weeks. I also learned a great deal about why I was such a strange person growing up. 8 months later and I am still trying to pick up the pieces and fix my life and I am very, very scared that things aren't going to work out for me this time. Lost my stipend/income, lost a professors trust and an amazing research opportunity, tried to find a job but cant because of my gap in history, will have to pay for housing using financial aid (if I get my aid in time - otherwise I'm screwed), I accidentally enrolled in a summer course that I never took that I now have to pay for (with the money I don't have) and am not sure if I can get it off my transcript. On top of that these past few months have completely killed my self confidence and drastically changed how I feel about the whole "working hard pays off, honesty is the best policy, value integrity and respect" life doctrines.
Sorry to hear it, Aero. I've known people with mental illness, I have a lot of empathy for them -- having to deal with ineffective medical treatments and social stigma .
You have a diagnosis, though, right? You should go to your school and explain. At the very least, they should get that summer class off your transcript.
