Is it possible for anhedonia to go away?

Maybe: Anhedonia, the inability to experience pleasure can be a very serious mental disorder. Everybody gets stress and "bummed out" once in a while which makes life seem unpleasant. That goes away when the stress goes away. True anhedonia can be relentless and lead to suicide. If you have it, get help. It can be helped but you need to take the first step.
