My mum has just run away from home, and I have texted her and she says she is safe but will not be coming home tonight. My dad is not doing anything about it, and it is my sister who has caused the whole situation. For the past two years my sister has been suffering from an eating disorder, and my parents have been unwilling to get professional help until yesterday. However, this has caused many problems for my family. We always argue, and the dinner table is not a place of laughter anymore. My sister is unwilling to change. The worst part of it is that I feel really depressed at the end of the day and sometimes think of suicide. I am not an attention seeker, and to be honest I am happy without the attention, and would much rather have my sister cured and my parents happy, than get the attention, but I still feel like I am lacking something, and gets me really depressed. What should I do?
