Yes, my T told me it's very common for one to switch from restricting to binge eating. It's even common to switch week to week!

When I first started discussing this with my T, I was terrified that she wouldn't believe me because I'm a bit overweight now, but in high school and college, I was underweight and restricted my eating. My T never doubted me.

For me, working with a T has helped. But, you have to find the right T. Someone that understands disordered eating, someone that you connect with, someone that you trust.
