Jully, call back and leave another message; your T may not have gotten the first one or something. It is a "business" arrangement like other ones; you'd call an insurance company or utility company if you needed something from them, therapists aren't a whole lot different. Just leave a pleasant, light message like, "Hi, this is Jully. I'm not sure if you got my first message on Thursday; I'd like you to give me a call at your earliest convenience please at 123-555-1212."
