Hey. I hav been experiencing this for four years now. I got this frm the trauma of being bullied at secondry school for 6 years. I seen a psychologist last year about this and she said i had PTSD and we began psychotherapy for 6 mnths. it was great but i still feel in a dream, my ears ringing etc, any help ? Its horrible living everyday with it. I need some help how to get rid of it . thanks
