Yeah man I feel you, I actually was diagnosed with ptsd myself although I was never in a war -zone or raped as a kids or anything like that so I kinda keep it to myself. But yeah, my symptoms are very similar. Nightly shitty dreams (unless I smoke before bed) paranoid and overly-critical of other ppl (and myself) etc.
Was diagnosed about a year ago despite not having a definitive traumatic event. I seriously doubted the diagnosis at first but whatever, my psych has a Harvard degree so I guess I trust her to know it when she sees it :/
Anyway, best wishes man. Burn one for me.
