I am having racing thoughts and memories are being mixed into scary things I’ve never seen before like being electrocuted by a doctor (I really went to a doctor) as though I’m not real and had to be jumped with cables and they were mad I could witness it but brushed it off as though I probably wouldn’t say anything. I’m just seeing lots of teeth and fangs when I close my eyes and faces too. I feel sick like maybe I have cancer or something worse. Is this a panic attack? I feel really scared.
