I'm sorry for what you are going through. I understand the feeling when apparently everything goes smoothly and your inner world becomes devastated and then it starts interfering your external life as well. You should discuss it with your therapist. Nobody will consider you crazy. You sound quite a sensible person and being neurotic doesn't mean that you are going to be psychotic as well. Keeping all these things inside makes you feel even worse. I wonder if you express when something bothers you? If not then start expressing now. You'll feel better.
Wish you good luck!
