Just a thought, why would you want your old life back? Is it because you are scared of the unknown? We are already at the bottom of the ocean, so what are our options: stay down there and feel this way for the rest of our life OR trying to swim back to the surface?
I know you can't see it now, but it will get better. I'm nearly one year in this, and I'm not there yet but life is better then a year ago.
