I'm not an older student, but I have returned to school after starting and stopping several times. I always wondered why I couldn't get through my classes and was unstable for several years. I've been diagnosed with Bipolar 2 and what I can recommend is to make sure you're stable on your meds to get through it. Since I have been on pretty much the same dosage the past three years, I have been able to get through my bachelors and I'm graduating this fall. It's never too late!! Good Luck!!
