I think "fear of getting better" is a worry and worries are always about the future, things that haven't happened and may not happen. We can't tell the future so the whole, "if I get better, this will be how it's like" thing is wasted effort as we can't know how something we haven't experienced yet will feel!

When I'm rich and famous, I'm going to give you $1,000,000, I promise! You counting on that?
