Hello SnappingRope: Thank you for sharing your concern here on PC. I see this is your first post here on PC. Welcome to Psych Central.

We here on PC cannot offer mental health diagnoses. Plus I'm not a mental health professional. (Most of us, here on PC, are not.) So I can't offer anything in the way of suggestions regarding what your correct diagnosis might be. (Perhaps other PC members may have had some similar experiences they can share.)

You mentioned PTSD as well as schizophrenia. So here are links to 2 articles by our host Dr. John Grohol, Psy.D., from Psych Central's archives, on these subjects:

I hope you find PC to be of benefit.
