My reason was slightly different for each of my three times going into therapy:

1. First time: Depression directly resulting from initial awareness of abuse.
2. Second time: I sort of stumbled into this one as just a discussion with the therapist. I knew him in a different context, and something I said sparked him to initiate more inquiry into my issues. We sort of developed into the therapy mode through this discussion.
3. Third time: Recurrent depression that was bogging me down. I wanted a therapist to help me get past the constant beat-down of depression, whatever it took. I was determined to walk through whatever fire I had to in order to get past my past; I was tired of my history running the show.
