Hi I am going through a similar situation except with my mum. My dad and I are really trying. Its so frustrating too, my mum does not want to attend anywhere for help. As soon as she is off the drink and sober she thinks she is cured and healthy! and then relapses the following week. I am also a student. I am doing nursing and surprisingly I’m at an alcohol addiction centre (out of everywhere they assigned me here lol) however I have learned so much! if you every want to talk, let me know. I live at home and live with my mum and dad. I’ve came to the realisation that we can only do so much to help them, its up to them to actually get help though, as hard as it is its the truth 🙁
