:Welcome to Wikipedia, Cordelia. 
 :Your edits introduce the incorrect idea that Carol Tavris is the only person in the world who ever believed these things.  For example:  "Writing in 1992, Tavris said that PMS was being mis-diagnosed":  Do you really believe that Tavris is the only person who believes this?  
 :Your edits also violate Wikipedia's rules about sources.  For example:  "This discussion is largely academic these days as PMS is a known illness, with hospital clinics devoted to it."  You cite the existence of a clinic that contains "PMS" in its name.  I could cite Royal London Homoeopathic Hospital as proof that homeopathy isn't pseudoscientific garbage.  Would you consider that to be a good proof?
