I Can't Stop Eating and I Don't Know What to Do

I've been a part of OA for about six or seven months and I really do love it, but I can't get myself to stop eating. I was going to meetings pretty regularly when I started, but I've had long periods of weeks of not going or sporadically during the week.

But I can't stop eating and I don't know why. I give myself a date where I will stop eating the crap and focus on my health, but I get so nervous the day before and fall back into these terrible habits. I really don't know what to do at all.

I'm in weekly therapy and recently was diagnosed with biopolar 2 and C-PTSD. I am take a GLP-1, but it really isn't helping anymore.

Does anyone have any advice? I haven't worked the 12 steps yet, but don't know what to do now. I'm not looking for medical, diet or exercise advice, but from my experiences with OA I know I'm not alone in my feelings and would to hear about what has helped other recovering addicts.
