I wouldn't want her to respond in an email! I would think that it isn't therapeutic given you ran out on the last appointment. You should go and just know that I can only imagine that she is completely professional and wants nothing but the best for you. I imagine that she was left thinking she may not be doing a great job given that you ran out. Perhaps she is concerned that she isn't being as effective as someone else might be? Who knows? However, you won't know either unless you go and hash it out. You have got this! I would want to speak to her face to face, but that is just me!
Good luck! You are strong!
