Vent

Im24 years old and for the last few months I've been looking after my younger brother. We grew up with our single mum until she died when he was only a child. They were very close before that and he took it really hard. We never had any kind of counselling and we were moved around to live with different relatives, none of which who were too keen to have us. We separated and lived with different family members for about five years but I always visited and called almost every second day. After getting into trouble with alcohol drugs and fighting he has come to live with me and I'm so happy to have him but each day is a horrible and devastating battle with depression. On days when I work he stays in bed all day. He doesn't even eat. He has started on anti depressants but he has taken every medicine under the sun and swears none of it works. He takes a lot if anger out on me and I'm finding myself constantly sad and worried and crying every day.i love him so much and I would do anything for him. But it feels like he has given up on himself and I just don't know what to do he has been my best friend our whole lives and I don't even want to imagine life without him. Please help!
