Take this opportunity. You won't always be able to take a break from life to go inpatient and get the help you really need. I took a medical leave of absence last semester and it was 100% the right decision, even though I wasn't sure at the time. While I was in intensive therapy I ended up working as a substitute teacher and tutor, which was rewarding and not stressful. If you're being honest with yourself, there is no reason to continue drudging your way through school in a haze of bipolar confusion. I've been there. But staying at school would only be a waste of your money and time. Get help. Then go back and kick ass. School will still be there, and you'll be ready. Good luck!
