So I am set to see my T next Monday but I have really been struggling the past few days with overeating (I say overeating...I'm not even sure if its true overeating its just overeating for me.)

I feel so bloated and gross and disgusted with my body. I also recently started 2 meds that are known to cause weight gain so im basically petrified and feeling like i have no control over myself. and the fact that I keep choosing to overeat only solidifies my belief that I'm out of control and need to go back to restricting.

anyway, I want to cancel my appt and reschedule for later! I feel like I need to get my act together, get back to my usual diet and fix myself before I see T again. omg even as I type it out it sounds ridiculous but I can't help it. I feel so embarrassed and ashamed to let her see me like this. It makes me sick to my stomach to think about. so my question is
1. Can i cancel??? Is it okay, is it unprofessional to reschedule? can I do that??
2. how do I handle the shame...I dont want to avoid her forever but this is a particularly awful week for me and I just do not want to go.
