Is it an ADHD thing to panic… when someone actually treats you well?

Okay, this is something I’ve been trying to unpack lately.
When someone shows me consistent care, kindness, and emotional safety… my brain freaks out.

I either shut down emotionally, overthink every little thing, or start pushing them away — even if I really like them.
It’s like I don’t know how to “receive” safe love without expecting the other shoe to drop.

I’ve heard this might be an ADHD + rejection sensitivity thing, maybe even trauma-related. But I’d love to hear from others:

Has anyone else felt this panic when a relationship starts to feel healthy?
How do you work through it without sabotaging something good?
