Then he definately needs more help than you are qualified to provide, Issy. If he attempted suicide then hopefully he sent out enough alarms to people who can help send him in the right direction.
That;s the thing, sometimes I really wonder about his family, he could be lying on the floor dying and some of them would prolly just leave him there if they were drunk enough
It worries me alot, they are not a happy family, ever... they are always screaming and fighting.... I lived with them for a year and I almost snapped
If he attempted suicide, and his sister told you, someone in the family is at least somewhat aware and interested in what is happening to him.
You can be worried, and concerned, but sometimes you have to take care of yourself first.
As hamburger often says "one hand for yourself and one hand for the ship". If you don't take care of yourself - you're no good to anyone.
You've proven many times that you are a nice, caring person, Issy. Don't forget to be nice to yourself in this instance.
