Maybe if you just see this as a simple scheduling enquiry rather than a reaching out for help it might be easier? From your post and I could have misinterpreted it, it read like you would contact her on her return to arrange a session. Generally they won't contact you as it is a clients job to schedule the session at least it is where I'm from.
I'm sorry your having so much trouble reaching out for help and I'm really pleased she's back and you'll see her this week. I hope you manage to send a text to sort this out. Thinking of you
