Respond with exactly how you are feeling. Be honest with him. Doodi, I am getting the impression fromj your posts that you may be suffering a depression. Have you looked into that yet? Have you suffered from it in the past? I would recommend that you see an IC if you haven't already (and an MC). An IC will definiteloy help you sort out all of these feelings you are experiencing (and non-feelings). The numbness is not a fun feeling. Coasting through your days - been there, done that.

Writing = very good. Have you tried journalling?
