I'm 48. I was diagnosed at 25. I've been on meds since then. I don't feel bipolar is related to age, but more to life circumstances. For example, i had a real hard time in my early thirties after my ex-husband divorced me and i stopped working. My bipolar was most intense then due to poverty, homelessness, destitution and of course, not being able to afford meds.

Since i got back on my feet in my mid-thirties, life has been more manageable. Bipolar is a b&tch but everyone has something.
