i totally relate so much. i dont think its really "Rewarding". i think it just shows that your t cares for you and thinks about you when he doesn't get an email or a phone call.

my t does this thing where if i get through something hard, or do some really hard exposure work (for anxiety), she will bring me little treats (chocolate, etc). that is more of what i think is a typical example of a reward. im not sure tho that a phone call is rewarding tho...
