Don't worry, you'll make it, I went through that too, especially many of those rockers were famous when I was young, a long time ago, ha!ha! Now, I am 47, and still around.
Try not to allow yourself to get caught up in that mindset, otherwise you can really start messing up your mind.
Just follow your treatment plan, get talk therapy of some sort and things will work out fine.
Just believe in yourself, there is still so much out there in the world waiting for you to enjoy.
I was in bad shape about 5 years ago, even embracing suicidal thoughts, (long story) got help and have been following "the program" since, and it works
Just believe. . .
