Aw, man. That sucks. I don't think you really messed up. You told you W how you feel and she ran like a frightened rabbit.
Get your medical issue under control and try not to think about this for a few days. Take a few steps back, breath, and decide what you want. Don't throw in the towel yet. At least 24 hour rule, if not 48 hour rule, on this one.
She's been so up and down, tomorrow she may be doing a 180 toward you.
Good luck on the job interview. I'm sure you'll be fine.
