Can relate in part, my T wants to work on trauma stuff next month and I'm dreading it. That said though, these things are what effect some of our core beliefs, the stuff that is foundation blocks to where we are now... for any chance to heal and move forward, it is going to be a logical part of the process to look at, acknowledge and tackle these big barriers that we have repressed, have brushed over with lots of gloss paint and hoped they would just disappear.

Doesn't work like that sadly, they lurk under the surface and are instrumental in how we feel.

I would say that you have to let her know that if she/he insists on working these issues, that it's got to be at your pace. If you're not ready, then you're not ready.

Be gentle with yourself UM, she is there to help you, so tell her how you feel, let her know if something is too much... if she has any sense she'll chat with you in a kind adult way and discuss how to progress in a way that you come to an agreement that fundamentally, you're comfortable with.
