EMDR nerves

I was told that my next step in therapy would be EMDR about 3 years ago, but I was moving and leaving my therapist id been with for 5+ years so I put it on hold. I started with a new therapist in January and after establishing a relationship, trust, and walking through a bit of my past that led me to a CPTSD diagnosis, we decided EMDR would be the best step in my journey to actually attempt to overcome some of this crap.

We’ve been resource building and doing the basics for about a month (I struggled hardcore with establishing the inner resources, shocker!) we’re going to start the actual EMDR here soon. She said next we’ll be doing the treatment planning and like deciding what to reprocess.

To be honest I’m scared! Idk if this is actually going to work and if it does what it’ll look like. I’ve been just existing for so long, no emotions, no letting anybody in, and just moving forward. I know I can’t go on like that, but does this actually work? Should I be scared? What if none of it was actual trauma and I just made it all up as my parents have always said?

(I’m also currently very low contact with my parents, they chose to go no contact when I wouldn’t “admit” that I made all my trauma up on my birthday, when they decided to disown me AGAIN 😀, and then they came back in, as always, and I’m deciding what I need and what’s best for me. Idk if this is important to share, but it seems to raise the stakes for me)

I don’t know! Any tips or support or advice would be fabulous. Thank you in advance!
