I did this recently. I was just in such a bad place over my T going away that I genuinely felt like I wouldn't survive (obviously I did!) and I just needed something in place, someone in place. She chose someone and let him know I would call, and it felt like a connection to her even though it wasn't her. Of course it wasn't like seeing her, and it was quite an odd experience for me, and I ended up dissociating quite badly during the session...but I think I would've been worse without it. It's probably worth a try if you feel like you really need the support at the moment.
