you sound so much like me... i often have to call after session to be sure he's not mad or upset with me.

having her gone for a medical reason has to be scarier than a vacation but when my T was on vacation there was one thing he did for me which helped so much... i asked him to leave me a voicemail. i asked him a question about something important to me and had him answer it on voicemail. i clung to that.

so maybe a voice mail which addresses your specific insecurities...like whether she is angry, or wants you to go away, etc. Having her voice to listen to might be very soothing
