Kagamine,
I've gotten into this dilemma off and on throughout my life, but never recognized it as a side effect of the PTSD until recently. It happens when I'm overwhelmed with stress. I moved to a new state last March and started seeing a new T later in the summer. My stress levels were so high she was trying to talk me into considering hospitalization to remove the outside stressors.
For me, going into the hospital felt a lot like complete loss of control and freedom yet at the same time, sounded like the reprieve I needed. I had to have some relief or it felt like I was going to have a heart attack. For years, I have been avid about eating right, hygiene and exercise, and quite frankly, this is what has probably me survive so well over the years. Because of the stress, I completely lost the interest or ability to take care of myself, all my healthy habits went out the window. I was lucky if I brushed my teeth, ate for a whole day or bathed some days. I didn't care, or at least I didn't think I did. Then I started drinking and smoking again (still smoking but taking it one day at a time).
My therapist explained how not eating affected my sleep patterns and anxiety levels from a physiological perspective. Those words gave me a small sense of control over my PTSD, body and soul. And it gave me a sense of control over not having to go into the hospital. I just set the thought in my head that I wasn't going to give up. No matter how hard it was, I forced myself to take bites of food at normal meal times. Sometimes I had to write notes to myself or put it on the calendar but each day I did it, the easier and easier it got. And, the best part of it was that I FELT BETTER!! I trained myself to listen to my body, it can be really hard for some of us. My stomach used to growl so loud that other people would ask me if I was hungry and I didn't even realize my stomach was growling.
And as Captain Kirk says in an earlier post, Don't give up!! We all need each other here. As hard as it is, remind yourself that this is temporary and you want to be healthy when it passes so you can enjoy life. Take care of yourself, you are worth it!!
