I have been seeing my t for 5 months now and left a message asking for her to call me if she could for the first time last week. It wasn't an emergency but it was important for me to get her support after something very triggering happened. She called me back right away and we talked for about 15 minutes. It was really helpful but I don't plan to call her unless absolutely necessary on rare occasion. She doesn't do email except for scheduling due to confidentiality concerns. Texting is not something I am interested in but I doubt t allows it anyway.
