I think you are strong enough to get through this. i know how offsetting that can be, to be feeling good about something, and then have someone mess it up. but I think you should try and see it as another "minor setback". and not dwell on it, as you will only make urself crazy. You can do it! you have done it for this long; you can't give up now. maybe send t a message asking her to not contact you unless you initiate the conversation? explain why, and see what she says. i am sure that she will be so ecstatic about the progress you have made, that she will be willing to do whatever she can to help you suceed.
