My ex-gf keeps calling me crying and sending text saying she will OD, shoot air into her veins, just terrible things. She use to cut herself and has had issues with substance abuse. I told her we were done due to all the stress she brings on me and all the fighting over minute bs. She has alot of xanax since she is prescribed it but also abuses it. She says she wants me to say I love her or she will end her life. I tell her I love her and to relax. What should I do? This is happening right now, any help please.
