All the texts I send are in some kind related to scheduling. Either it's something like 'I'm gonna run late', which I just send when it's appropriate. Might happen a couple of times a year. Or then it's something more serious, like that I'm really struggling and don't know how to get through until my next session. In those cases I get a text back with either an offer for an extra session or a phone call. Those texts happen about once a month on average.
