A lot of great advice here. You're fortunate to have caught it early. At least now you have a path, a way forward. What therapy to go for, what meds to take, the right questions to ask, and so on. I spent my whole life bouncing back and forth from depressive lows to manic highs thinking I was broken, or flawed on some fundamental level, only to finally be diagnosed at 32.

Bipolar doesn't have to be a curse. It is treatable, and I have no doubt things will get better for you!
