Why do you need him to sign those documents to get a scholorship? Im just asking so that I can understand your urgency. I would say if he hasn't returned phone calls, he is probably just busy and even though it is urgent, I wouldnt continue to text. I would go by and just ask if he can fill them out asap. But Im not sure texting is such a good idea, for one, you cant be that sure texts get to him and another, even though therapists have been doing that. Its actually frowned upon and looked at as a slippery slope to blurred boundaries on your Doctors end, not yours. Really in a proffessional setting, a phone call or going by is the better thing to do and when you finally do talk to him you need to ask why if he has said texting him is ok, then why is he not responding. Because not answering back once is one thing, but over that he owes you an explanation. It is frustrating to not be answered back and in my book its unproffessional of him to ignore you, but in my experience with therapists, I would say I have met more people in that field that dont know how to be proffessional and tend to be inappropriate in handling business. So I would make it very clear that you pay him and if he isn't going to do his job, you will find someone who will.
