No where to go

I suffered with bulimia for a about 2 years and “recovered” sometime last year. I never got diagnosed or even told anyone. I did it all by myself and it was hard as hell, but today I looked at a picture of myself during that time and it triggered me because I feel like I looked so much better then than I do now and I don’t know what to do. I want to purge but I know I shouldn’t and I don’t know where to go or who to turn to because I’m scared I might do it.
