question: I'm 19, overweight for my 5'1 height and have hypothyroid which I am taking medication for. I was recently in a car accident in May of this year and was diagnosed with PTSD. A lot of anxiety symptoms followed. I have gotten a hold of the symptoms, but mainly it's stomach pain recently. I just wanted to know if that could be caused by bad posture? When I sit, I slouch for long hours, and don't really move a lot. I know that stomach pain is a symptom of anxiety, but I have always wanted to know.
