Darren - you are so articulate. I am convinced your feelings aren't 'dead' (which is what I feel you are trying to say) - I hear clear evidence in your writing that you feel very deeply, otherwise I don't think you'd have been able to write this post.
My feelings, smiles, laughter, playfulness, all live in the little kid inside me. She was so sad and scared when we were actually 2-7 yrs old, that I've had to have conversations with her in which I promise to take care of her if she'll confide in me and tell me when she feels bad. The adult me has learned to treat her with respect and to take better care of us; as a result it seems she trusts me more and the feelings come out. She's coming out of a deep freez brought on by that terror and sadness, so it takes time. And I had to look very deeply to even find her in the first place - she was deeply hidden behind the numbness.
My wish for you is that you could find a quiet place and try to contact your little kid who, I'm sure, is very frightened and un-trusting at this moment. It can be scary to touch that place for the first time, so perhaps take a trusted guide with you.
One day at a time, Darren. Please take care.
