Hey Catalyst,
I actually enjoy my phone sessions, but then, I was one of those preteens that spent hours everyday jabbering on the phone with my friends, so it's a mode of communication I'm pretty comfortable with.
I think in a way phone conversations can be more intimate than talking with someone in person, because their voice is right there in your ear, speaking directly into your brain, as it were. And without all the non-verbal cues, the nuances of the voice are more weighted with meaning and noticeable-- it calls for a different kind of attention. Think how it would be to have a conversation with somebody if you were blind, maybe.
That said, I think it's probably easier if you know them in person first, because that familiarity is there-- it's not a disembodied anonymous voice coming at you like when you talk to a stranger.
I usually go in to see T at her office, but I've had a number of phone sessions too. There have been times I was ill for extended periods, or recovering from childbirth, or just unable to get a babysitter. When that happens I usually will have a phone session during their nap time.
I like to closet myself in my room when I'm doing therapy over the phone. That way I'm in a familiar, comfortable environment. I can focus and "go inward" for the duration of the conversation without distractions. Sometimes (often, actually) I absentmindedly doodle in my art journal while on the phone with T. I'm not at all artistic, really, but I find art therapy interesting and have read up on it and tried some exercises. . . anyway, so I'll often be doing that while we talk-- I find it helps regulate anxiety (which the phone can tend to kick up in a way) and unlock access to my emotions, at least a little.
Then there are the times T says she's going to call and doesn't. . . but that's a matter for another thread.
HTH, good luck!
