Bipolar 1 here and I don't have enough data. I only found out I had bipolar 1.5 years ago, though I've had symptoms all my life. I don't know how many times I've gone manic because I didn't know it was mania until a doctor pointed it out to me. I would say the depressive episodes have lasted longer and felt worse in general. I assume there was more of them. I don't know.
