anyone else deal with depersonalization/derealization?

I'm becoming more attuned with myself as I age and more secure in my identity, however, whenever I am stressed out badly, I lose myself a bit and get really bad anxiety and physical pain. I feel not like myself. I know this is trauma, but I feel a bit lonely in this experience.

I was wondering if yall were willing to share, and let me know it's okay and I'm not alone, and that it gets better if it has. I feel like, if I'm not alone in this experience others may need to (maybe that's presumptuous, but here's hoping)

Thanks
