Could use some help/support if TRE is worth continuing for me

As far back as I can remember I have always had this low hum of discomfort, stress, and anxiety in my body that has only ever gone away when I've been in a relationship. Since my last breakup I having been testing different modalities along with therapy to see if I could make some kind of improvement and ease this feeling for myself.

I joined a program led by a TRE certified provider and my first session I finally had the kind of release I had been searching for. Anxiety I was currently dealing with immediately dissipated and I felt great well into the next day.

After that first time I went on a vacation for a few weeks and I never felt that release again. Every session since has had very mild to visibly unrecognizable tremors and I've felt pretty much the same afterwards, maybe a little tired or slight soreness in my inner hips.

Reading through the wiki I would think I'm too early/inconsistent in my practice to have hit a plateau and based on my schedule/feelings I don't feel as if I've overdone it. Over the course of 3 months I was generally doing sessions 2x a week, 10 min each, and spaced several days apart but I've also tested skipping weeks, every other day, 1x a week and I'm barely tremoring and seemingly no improvement in my general day to day wellbeing.

I'm started to feel defeated as it's getting close to a year of intentional nervous system work and just that one session of TRE made me feel like I was finally moving in the right direction. Now it feels like I've just made myself more mentally aware of my body and emotionally just keeping my head above water. Following some of the progress in this sub had originally been so inspiring and I cant imagine I could an outlier but I can't figure out what I could do next to get back and build upon the original benefits I thought TRE was giving me.
