I've tried to contact my previous T and later felt embarrassed about it for various reasons. There was the time she later told me she left her phone somewhere for several days and didn't have access to it. Another time, she ended up being out of town for a family vacation in a place with poor reception so the calls didn't go through. And probably a bunch of other situations I can't remember right now. Just try to accept the situation and move on, there's no need to blame yourself. He likely did not have his phone with him or even on if he was at the hospital, so it it doubtful that your calls were "bothering" him. Recently, i went back to visit my old T and towards the end I apologized for contacting her so much after I moved (emails, calls, and texts for a few months). She said, "Whatever you think I think about it, I don't." She explained that all the judgment I had about it was coming from me, NOT from her. It was comforting to know I really wasn't bothering her, that she can take care of herself, and to recognize that the judgment was mine. I would encourage you to look at your own situation like this too. It's okay to reach out for help and he responded to you as he feels comfortable. Big hugs!
