My therapist and pdoc do not text or email. If I need to speak to them between appointments, I call and they get back to me that day. We can actually have a conversation. They can hear my voice. I can hear theirs. We can ask immediate questions of each other and not have to wait for that return text or email. Personally, if something is going on as serious as being suicidal, that isn't email or text material; that needs a phone call. Sounds like you therapist handles contact well and appropriately.
