Controlling stress to focus on weight loss

My thought is I worry I will never be able to control my stress level and therefore lose weight. I am trying to work through thought models on this but get anxiety and therefore feel stressed. It’s a vicious cycle.

I’ve been working through this for years and some days without even realizing I am triggered.  I practice mindfulness, meditation and you name it.  I guess my thing lately that I’m really facing is trying to actually stay in my body and face all the sensations, feelings and thoughts I’ve been suppressing for years.  I just really want to make peace with my body.

Where to begin?
