Things can get hard some times and making decisions on what to do is difficult. If you can stick with school, try to do it, but not if it brings you down. The only reason to try to stay with it is that the more you can keep to routines and schedules, the more helpful it is to manage being bipolar. That said...you also don't want to set yourself up for failure, so push but not too far. Therapy once a week is awesome. Depending on where you are at with your medications, 2 months is good for a psychiatrist when you are stable...1 month or less if you are making adjustments/changes.

Stay strong and things do balance out in time. It might take longer than you'd like, but it will happen.
