If you are bipolar, depression can greatly impair your ability to concentrate and remember things. Only a tiny bit of antidepressant can help. But be careful with SSRI's as they can induce mania. When depressed, one doesn't simply not remember things.....it's that they never get into the memory to begin with because the concentration factor is so low. If you are going to attempt something as challenging as schooling, I would greatly consider assisting yourself with meds. Please, dont' misunderstand me...I think going unmedicated is great and I applaud your accomplishment. But the added stress may make your life very difficult. So you have to weigh which is more important to you. You could always return to your unmedicated state after obtaining your degree. Only a suggestion. Best of luck to you.

PS: As I said earlier, there are a zillion medications out there and a combination that is just right for you might be waiting.
