I feel the same way but with emails. My T let me use texting only once for something specific and that was it. With emails my T tells me to email anytime I need no matter what it's about but I try to limit it because I have a huge fear of judgement and I'm just afraid to annoy/bother my T. Over the course of the year that I've seen my T I would say I've sent about 6-7 emails about issues and the rest were just to schedule appointments.
