Ok so here is my story. The first ever panic attack/anxiety I had faced was after an acid bad trip which was three years ago. I seemed to be fine after a few weeks but exactly two months later I had an argument with a stranger and it gave me a serious anxiety attack which lasted three months. I started taking Lexapro and thankfully it helped me become normal again. After almost three years of taking Lexapro, I decided to taper off  (with consultation of my physician.) While in the process, I had a huge argument with my brother and it triggered anxiety attack that I thought was gone. It brought back all the bad memories and traumas from the past and my brain automatically keeps ruminating it. Although my brother apologized to me and everything whenever I see him I start blaming him and bear a grudge against him. I just want to feel normal again and all these rumination to stop. I fear that I have become to vulnerable. Whenever a person say a negative thing to me, it feels like I got bombed by nuke in my heart and aftermath follows.
