mona, i don't think you're overreacting. i would feel a bit weird about a former T looking me up and behaving unprofessionally like that. you only just recently stopped seeing her so it doesn't seem appropriate to me for her to friend you, let alone, then unfriend you. i guess she realized her mistake but since you just terminated or took a break with her (not sure what your status is with her) it seems kind of icky for her to be wanting to know what you are up to now. i'm honestly not surprised she would do that though from everything you wrote about your therapy with her. i know she was helpful to you in some ways, so i think it's good to hold onto that and let go of the rest once you've had a chance to process it. try not to get stuck in the bad parts.
