Lost at the moment

[lfm]

Hey gang,

In some serious need of advice at the moment. Just got a text from my W:

"Just wanted to say hi. Hope ur day is going well? I know u probably don't want to hear it but I'm having anxiety over what I've done. I've had this before but it's worse today."

I'm really not sure how to respond to this. Any advice from successful DBers out there? I mean I know I need to validate her feelings, but don't know what else I should say if anything...
