Anyone else that regresses involuntarily?

I (15F, 2-3 when little) regress involuntarily as a response to my childhood trauma. It happens very randomly, and there’s nothing specific that triggers it, but mainly happens when I’m feeling sad, mad, stressed or overwhelmed. Regressing is actually very comforting for me, and I’ve started feeling a lot better after a depression episode because I’m more familiar with regressing now and realized why I suddenly become so childlike in certain situations. I’ve started regressing on my own/on purpose in times where I feel a little down, and that’s really comforting too, but most of the time it’s involuntary.

I’d just like to feel a little less alone by knowing others who are the same and how you guys cope :))
