I went through a phase of wondering, and asking, and then later explaining, why we do what we do. It seemed important at the time.
I never got a fully satisfactory answer for, nor did I clearly explain to anyone else (not even my therapist), what is going on.
The CDing carries on regardless. It does not require detailed explanations for it to work.
So I've given up. I CD because I like to, because it fulfils me in some way, and there's an end to it.
Why should we explain ourselves anyway? We're just part of the overall picture (and quite an attractive part, may I say).
