I don't think it goes away per se, but I do think it can be managed. There are people, as has been said, who go for years without an episode. Maybe your backpacking trip helped, maybe we should all get out more in nature and walk tons, I know the little I walk in nature helps me a lot.

But please enjoy your stability and don't worry about your diagnosis or what might be to come. There's a lot to celebrate here and I hope you do!
