Maybe add a trigger? But it's misleading that it's triggering. Ask a moderator?

If you saw an EMDR T, they would use that technique to banish those feelings about that time forever. What you're going to do sounds like it's going to do the trick, though. Good luck with it! It sounds like you DO need to revisit the past, first, and that IS a reason for your therapy. It will be painful, but I think it will be productive for you.
