Gosh, that is insane! How creepy! Glad you had the locks changed!
Not sure what I can add or advise, but do you have a primary care doctor who can prescribe something? My PCP prescribes all my meds. The last place I ever want to go is the ER. I think it is crazy that they recommend you go there vs. them managing your care and meds. Also, I can't believe they will not prescribe you something with having the police report. Did you speak directly to the doctor or just the wolf hounds that answer the phone? I have found that talking to the doctor directly gets much more accomplished.
Good luck to you! Hope you do not have to deal with withdrawal!!
