A group therapy each of them for a different self control problem decide to take revenge after hearing the new member story.

This doesn't read properly. I'm confused as to what the story is actually about. Check out the "Our formula" tab for help with formatting.

My questions that I have currently:

1. 1. Who's the protagonist?
   2. Who is getting revenge against who and how?
   3. How is this a comedy?

Once this logline is in a more conventional format, and at the very least provides answers to 1 & 2 above, it will be easier to offer more feedback.

Fwiw, I do like what I think is the idea behind this. I need more information to understand it better though.
