Sometimes I bring something up and T laughs, and I wish she wouldn't.

Like for example, i mentioned how i used to cut. I said i did this for about a year and I stopped because it started hurting. She chuckled at that.

Maybe she thought it was meant as a joke?

IDK, it wasn't a joke. For me, SI didn't hurt when I was into it. The hurting meant that I no longer needed to SI.

That's what I wanted to convey to her.
