For me 15 weeks were way to long to go with out an episode. I had gone 10 years, off and on, trying to get through school. Now, if your in the U.S. you only get 6 years of financial aid if your full-time and 12 yrs if your part time or a mixture of time if you mix full and part time. I have learned I can only handle 2 class at a time before I flip **** mid semester but I kick butt in those class because I treat it like a full load. If you live in the dorms you can get an exemption from the disability office saying you only have to take part time to live there. However you'll only get part time funds so you may have to do work study and a payment plan. I hope that helps a little.
