Sounds like you really have your hands full. My first question I think is where is she getting all the Vicodin from?????? If she has an abuse problem and it sounds like she does then I would try to find out who her doctor is and maybe have a chat with him or her. I hate this for you and for your g/f as it sounds like she is really depressed and in need of detox from pain medication and maybe trying a new antidepressant if her current meds are not helping her depression.
