I don't think you have PTSD unless you have an unnamed qualifying trauma from your past and this stuff just stirred things up so to speak. PTSD is only caused by certain events including sexual trauma (rape, abuse, molestation), actual or perceived threats to your life, etc.

It sounds like you have anxiety issues. PTSD is to anxiety as a stab wound to the gut is to a paper cut. They are indeed worlds apart but along the same spectrum.

Ultimately, its good that you probably don't have PTSD.
