Barb, i'm so sorry, and it seems you loved your brother very much, your love for him comes through in your posts. I do know, that when someone does this, it is no reflection on you or your family, or what you could have done or not done. When someone does this, it is not that they want to die, they just don't know how to go on living. It is a medical problem, an illness, a chemical inbalance, like you said. It makes me sad that the system does fail some people, or they aren't able to get the help when they need it, for whatever reason. Your bringing this up brings knowledge and hope to the situation. And i believe where there is knowledge there is power. So you continue to fight to bring more knowledge about mental illness, and your fight won't be in vain (((hugs)))
