People keep intentionally startling/making me flinch 😭

Honestly, I've noticed that I get startled/flinch extremely easily. like even barely touching me to standing behind me and even calling my name evokes a strong reaction. People have noticed and some people keep intentionally doing it 😭

Like I get it if it's accidental and I wouldn't really mind much, but it feels so exhausting when people do it on purpose just to amuse themselves.

But honestly I can't even blame them because they don't really know my history and I'm definitely NOT telling them what happened.

any advice appreciated 😭
