Hang in there! You have lots of friends here who know what you're going through.
The quickest way to ease the helpless feeling is to DO something just for you. What do you like? Watch a movie, or take a walk.
Also, you have some feedback from W on what went wrong - use the opportunity to improve yourself and you take back some control over your situation. The worst thing would be for her to say you did nothing wrong.
No need to be ashamed of the past - work toward a better future.
