I used to pay my T $50 a month for emailing her. It was kind of a requirement to email everyday. I had a standard form that she and I (mostly she) made up. It was just stuff like, did I eat, take meds, have fun, how much sleep I got, my mood... I also could write stuff to her as well. She always responded, sometimes with short replies adn sometimes long.
I was very lonely and not really taking care of myself at the time, so I found it helpful. And I didn't feel like I was abusing it or taking up her time, because I paid the agreed amount for it. I'm sure $50 was nothing to her, but it's all I could afford.
However, one can get very dependent on a T that way--daily contact and sometimes I'd email her more than once a day. I didn't have any friends and I think it kept me from persuing some. I don't think that was helpful.
I stopped seeing her because I moved. But I don't and don't want to have that with my T, just for that reason--don't want to be that dependent.
