No, it is possible to get out of it. ANYONE can, even you.
I also thought the comment doubting your previous illness was rude and just plain wrong, but I am not sure about this line in your response. Because...
remember everyone is different.
We have different life stories and genetic predispositions. I don't think we can say that anyone can be cured, because many people don't get better. And it would be wrong to claim that it's because they aren't trying hard enough. You know what I mean?
It's great that you got better though, I really enjoyed your story and its final image of you having an awesome time surrounded by big big speakers. Keep it up!
