I think you deserve kudos for not only realising you had a problem while still in your twenties but on taking action and getting yourself educated. I sort of have the opposite problem; emotional carnival while drinking, numb once I got sober. Sex was out of the question at first, after three months I feel my drive returning, but intimacy is still scary. Laughing took me a while as well, for a month or so I would honestly *think* something was funny but the only reaction I could muster was to say,"That's funny". I like this quote from Bob Egan, an American Jesuit:
"Out of the rush of new life, of unfrozen feeling and liberated imagination, comes a longing for something more, for a restoration of wholeness in our lives and a connection with a deeper source of life that could enable us to be real human beings."
