I haven't been diagnosed but students at this stage, we all feel burnt out, we really don't know where our future will be like regardless, and having bipolar can make it more difficult, dealing with the uncertainty

It is fine to question your future, but don't drop out of school, you're so close to graduating. You'll feel better once you get the degree. FOr now try to take time for yourself to answer your own questions, if it's possible can you go to a college counselor? They know it's a stress going to college..
