I remember the first visit with my therapist, she warned me "things are going to get worse before they get better" and she was right, but I'm in a much better place than I ever thought was possible. It was a lot of hard work and a lot of introspection having to face my inner self was so difficult but something that I needed to do. For years I felt like such a fraud, that I was faking my way through life, and in many ways still do, but it's hard to deny that I have accomplished all of the things I have accomplished. It was you that went through college, "hollow shell" or not you did it. You did that and so many other things, it's all YOU, you the "shell" you the "15 year old recluse" they are all part of you. Don't try to deny them, or fix them, accept them, be kind to the 15 year old recuse, fill up the hollow shell with love.
