I have a very low ACE score, but EMDR is really helping me out with some little T traumas. It's so individual.
For me, EMDR is a real process. When I'm asked what I feel, I generally say I don't know. Then my therapist will back it up a bit and ask if I feel anything in my body. She says sometimes feelings that we've hidden are still stuck in our body. Some times, I still feel nothing. Other times, it's something super small like shortness of breath. As we continue, this often brings up more body sensations and sometimes even an emotion that I can name.
There's no right or wrong way to "do" EMDR. But for me, I needed to fully trust and feel like I could open up and be vulnerable with my therapist before this process could even start. That took me 2+ years.
Good luck!
