I'm positive that it's ok for you to go next week- and I'll betcha anything that this has been WAY harder on you than it has on her granite. Call her. Explain all of your feeling to her. She needs to hear more than is it ok to come next week. She needs to know why you're feeling like it might not be. You wrote down your thought process brilliantly. Share it with her. I think she'll appreciate it. You are really suffering right now. Do you think your T would want you to suffer like this?
