This may not apply to you because I have CPTSD but it sounds a bit like being triggered. I don't react like that but I know some people do. I'm just mentioning this because if your issue is trauma-related and deeply rooted in your nervous system, as opposed to being a more normal-person mental health issue, CBT is not the right choice. Nor is exposure therapy. You need treatments meant for PTSD specifically and those that are not can make things worse.
