I know that for me, eating disorders have always been apart of my PTSD, although I have not always been conscious of it so it's taken a lot of work to really 'see' this. I didn't just take one person's word for it. I would probably be doing a lot of reading up on eating disorders and how they relate to PTSD and what the symptoms are. Has your tdoc given you literature to read about Eating Disorders? Have you stopped eating like this before? Do you see a pattern?
These are all things that would be important to look into and take a good honest look at. I looked back and saw that even as a teen I was bulimic and had bouts of anorexia. I hadn't thought much about it until one stretch when I went 4 days without eating a single thing and mentioned it to my tdoc. My ex husband had done something that tore me up and I just could not eat, didn't want to, wasn't going to, felt in control in a powerful way and I didn't want to lose that feeling. He was shocked to watch me start to loss weight so quickly which only served to make me feel stronger!! It was the most incredible feeling to see him so helpless to stop it. What I wasn't noticing that while I was so pumped up I was actually hurting myself, I didn't get that, I didn't understand because, for me, that is the 'high' of anorexia. While it tears away at your body feeding on itself, you are filled with a sense of invincibility. Four days turned to nine and as I was falling apart physically, I started to fall apart mentally and emotionally. I didn't sleep at all, I became completely obsessed with the scale and what not to eat, my body, nothing else matter, it became my whole life, keeping complete control was everything. My hair started to fall out, my kidneys ached, my stomach knotted up, etc. All side effects of starving the body.
I don't know what your tdoc and you have discussed or what is going on but if you have questions it's always good to get as much information as you can. It sounds like you know the answer about the control issue with it. It's good that you are looking at that part of it because it could fit. Please take care of yourself.
Hope this is somewhat helpful.
