Today, for the first time I can remember I felt like myself completely. This is not to discount happiness I've felt in my life, I've had great joys. I think it's like someone's been telling you you wear a size 7 shoe, and your feet ache and your uncomfortable, but not enough time to really do anything about it. You have too many things, to many good and bad things to worry about to deal with the ache in your feet. You're just used to it, you don't have a name for it, and you don't want to delve further into your past to figure out why. 

Then one day someone gives you a size 7 1/2, you slip them on and your life changes instantly no more pain, and you have a name for why you feel the way you do. 

This is probably not everyone's experience, but man do I feel wonderful.
