I have this internal angry teenager. Mad at the world. Mad at me.

This part usually acts out by not talking in T or arguing with everyone around until people just get sick of me and just leave

Or when start losing weight this part starts binge eating. It is like every step forward, this part wants to drag me backwards

Lately though this part is so angry that started to cut. I can see it happening, like I am observing but can't do anything to stop it

Not sure what to do. I not sure how to tell T about this, but I know I have to.
