Does she have a counselor or therapist she can call?
If you are really worried or she sends you more distress signals, you could maybe reply something along the lines of 'This is worrying, I hope you will contact your counselor/therapist as soon as possible.' It should signal that you care, but can't fix it.
If that ticks her off, you'll know it was drama and attention-craving acting out. If she's truly in distress, she will seek proper help.
She could be regretting her choices and not know how to recover from them. Shame is a very difficult feeling to deal with, and many flee from it in any way they can.
