We're both 23 years old right now and we've been like best friends since we were age 9. When he hit adolescence it became apparent that he started getting mood swings, except that they haven't really died off. That sort of thing is starting to affect his performance in school; he's rarely motivated to do his homework. He always goes into bouts of depression, often after doing badly on an exam or experiencing something else that discourages him in life. That leads him to do worse in school. Sometimes I'll give him a motivational one-on-one talk, which will lead him to study really hard for a period of time. Then it's back to normal again. He seems to be emotionally fragile and easily affected by daily events in his life. Hardships in life get him down particularly easily. We started university at the same time but now he's two years behind me and getting further behind as each term goes along. Today he told me, only half jokingly, that he was ready to quit his program and become a plumber. He's completely unfocused on school; he goes to class but sleeps through most of them, doesn't start assignments until they're almost due, and hardly studies for midterms. It's as if he's given up trying because he feels he does not have the ability to accomplish any better. Both another one of our friends and I have told him that he might be bipolar; today I mentioned it to him that maybe he should get it checked out and he shrugged off the idea. I'd like to help him, but am afraid that insisting there's something wrong with him or further telling him that he's messed up might make the situation worse, especially given his emotional fragility. Does anyone have any suggestions as to what I can do to help him?
