What does d/o stand for?

I had drug induced bipolar for 6 days. The mdma comedown was full blown euphoric depression and episodes of cyclothymic mania. I cried 40 times a day for 6 days so like 250 times I recon. When I listened to music, I would get the chills from head to toe.

People would consider it horrible. But idk what they're talking about.. For me personally, it was much better than anhedonia. Although I wouldn't like it to happen again.. Not now.

That's just my personal experience. Mostly since 16 until then, I had complete dysphoric depression all the time and agitated mania. Never felt euphoric.

I hope I don't get crap for this: I'm just trying to understand..
