I'm so sorry this is changing for you. I would really struggle with having just a generic coaching line to call and not always getting MY T. I struggle enough with just calling my own T...I'd never call someone I didn't know, and if I did call, I wouldn't say anything!

Could you maybe ask your T if he'd be willing to accept emails from you in between sessions? At least then you'd be getting him directly. Not the same as a phone call, I know, but maybe a do-able work around for a while. Maybe even suggest it as a short term bridge to not having the constant phone contact you're used to...kind of like weaning off of it.
