Hi darkblue
I have thought about this many times but to be honest I don't think you ever completely fully "recover" as you coined it.
I think though (and have experienced) that you will go through times of "normalness" because you've found a way to positively incorporate it into your daily living. By learning coping mechanisms and using them in your daily lives the symptoms become less and less until they are no longer... A beautiful thing... the best part being that you don't even know the "exact" moment at which it happens but find yourself looking back wondering when it became so good.
Like all things in life though, things change. It could be jobs, hormones, death of a loved one, illness, university etc. and because they are things that have never experienced previously you may experience a "setback"... but that is all it is.. and you take a moment to readjust, make the changes that are needed and again move forward.
So on a positive note.. I think you end up in a BETTER, more empowered place. You are taught to look within yourself and accept yourself in a way a lot of people may never experience. It is what gives you compassion, empathy and all those wonderful qualities this world is often lacking.
I've had wonderful years mixed in with a few setbacks.. but life is a learning curve and if you're willing to ride the waves and embrace who you are and not battle it every step of the way.. it will be easier.
I just recently had a "step back"... and it was really hard for me as I had thought it was GONE after years of peace.. but here I am a few months later with more lessons learned and another reminder of why I'm thankful for the life I have.
Hope this helps.
