To me your analogy with the chemotherapy is really spot on.

I have to go to medical therapies very similar to chemo. While I dislike both the medical treatments that I have to go through and the psychotherapy they serve the purpose of rooting things out of me that are harmful to me. Both have unpleasant side effect afterwards that make me really not want to go.

Since at this time therapy isn't life or death I have put that on hold for a bit.

I'm really glad that there are those that do really enjoy and look forward to it. Wish I was one of those.
