I have regressed after 5 years of healing

My trauma happened in 2017, December to be exact. For two years after that I was out of control, trying to cope with unhealthy habits. Then in 2019/2020 I got real help and started to heal A LOT! I worked through my triggers and anger, and anxiety and OCD, everything that came with it.

Recently, over the holiday season, I was triggered with a falling out with my brother and his toxic relationship. Some abandonment from my father came up as well.

It has literally sent me into a downward spiral. I worked through SO HARD to get where I was, and I regressed in a matter of hours.

Lately, I find myself so angry, drinking more, not leaving the house, crying, panicking, OCD thoughts have flared up. All this is happening while I’m in active EMDR therapy and I’m medicated, so I don’t understand. Nothing seems to be working for me. I feel so alone with my triggers. No one in my family or my friends understands really. I don’t have anyone to talk to about this except my therapist.

The guy I’m seeing tells me it’s ok to be open with him, but I don’t want to seem like a victim, bc this is all consuming and seems like the only thing on my mind right now.

I’ve cut ties with my brother and his toxic girlfriend. I’ve minimized time spent with my father and mother.

I feel betrayed or maybe I betrayed myself.

Idk…has this ever happened to anyone?
