When I was sectioned for six months, that was one of the worst experiences of my life, not being able to go out and have freedom. Having experienced it, it's almost inexplicably awful.
Depression is something that doesn't just go away. It's just... there and you deal with it. It's like... malaria or something. Maybe it won't be cured, but you've got to take the medication you're prescribed, and you stay out of situations that are going to trigger it.
I've never really been nervous about any concerts. I enjoy it so much. All that matters is getting the songs played well, trying to get them to sound as close to the record live, which isn't easy, because my music is quite complicated to play.
Antidepressants are very good, but it's a clinical cosh, really. Sometimes you have to be knocked out, just to stop; when you're in that state all you want to do is just sleep, and rest your body and your brain.
