Hi @Sabby
I can definitely relate. I left a long-term abusive relationship ten years ago.
I've developed strategies over the years that help keep me safe which I'll share below. If they don't sit with you that's ok; there are many resources out there.
Grounding techniques: I always carry a spiky fidget in my pocket which I squeeze in my hand during flashbacks. The slight discomfort brings my body out of the spiral and into the present.
Safe sentences: I have a series of phrases I repeat in my head or out loud (depending on where I am) i.e. "I'm safe now" or "It's over now".
Journalling: I write in a "trigger" journal using guided questions like 'Where were you? Who was there? What was happening? How were you feeling physically and emotionally?' Over time I've been able to identify specific sights, smells, words and thoughts that trigger a flashback; it's helped to learn that they're not random and there are noticeable patterns.
Keep in mind: Flashbacks are physically and emotionally draining. Make sure you take the time to rest and show yourself some love i.e. hobbies, a comforting meal, laying down with low-light and low-noise.
Regarding shame: It's completely natural to feel this way. If you've experienced gas-lighting and manipulation it takes time to sort through the lies you've been told and your truth.
Please give yourself credit for the strength it's taken you to survive and leave the situation. The journey will not be easy by any means, but you are absolutely worth every step!
I hope this helps even a little bit.
Take care 🤍
