Oh I'm so sorry you are going through this.

my heart hurts for you.
I had similar happen to me with the last psychologist I was seeing-- and when my appointment time came to see him.....I drove to a park near his office and I called him on his cell phone.... told him -- "I'm upset and don't know if I should come to the session"..... he said that I cna decide and that he will be there the whole hour as that is my time-- so.... 15 minutes passed..... I sat in my car at the park.... then 25 minutes passed..... I told myself then-- how will I know why he didn't email me back if I don't go and ask him?.... so when 30 minutes had passed I drove the couple blocks to his office and went in..... he asked "what's going on?" and I told him about how I'd emailed and never heard from him -- it was two weeks later..

He was surprised and asked-- "You mean you didn't get my reply?"... I'm thinking-- sure, I bet you're making this up..... then.... he pulled out a printout of my email and his reply was right below it on the piece of paper(he always brought the emails with him if I sent any inbetween sessions)..... he had sent one-- it just didn't go through to me.......
Well, I jumped to the worse thinking before I even knew the real reason-- the reality. I made my own reality that he put me aside like had happened to me all my childhood
Well, this is long-- sorry-- what I'm trying to say is that there could be a very good reason and it's not anything bad about you at all. I will hope that you find out soon and will then have some peace in your heart.
I'm here listening if you want to vent/talk or anything.
