"Exposure Therapy?"

 Hey Abby,

I just want you to know that it gets better. You build skills, and you learn to handle things one step at a time a little better than you used to.

You are capable of self-regulating, of enduring discomfort. Your mistakes are not catastrophic, and you're never going to become perfect.

You're not fixed, but you're capable, and you're not stuck.

And you're deeply loved.
