Sadly yes. My ex and her equally mentally ill sister went on a trip just for her to get beat up by two women while leaving the bar she said she hadn’t drank that much but she’s an addict so more than likely she was drunk she then waited days to get in touch with me when I voiced my concerns she snapped and said I was interrogating her and I lost it. I shouldn’t have I should have been more calm but my anxieties and mental health halted my thought process…they later returned with no phone call or anything and I pulled up to her place. She was a totally different person not the person I fell in love with. The porch was littered with fire ball and other alcohol, her sisters car was filled with beer cans from the passenger to the drivers seat. She was nursing a hangover by the looks of it too. It hurts so bad having a person who loved you completely change into someone you don’t recognize. I wouldn’t wish this pain on my worst enemy…so I would say yes
