can’t take life anymore

My life has been slipping away for a few years now.  My wife of 22 years has just left me and filed for divorce.  My kids want little to do with me now.  My once successful business is starting to fail.  I have no friends anymore because most were driven away by my wife and I let it happen.  My brothers and sisters don’t want anything to do with me because I ignored them for years because my wife hated them too.  My health is detiorating and I just don’t have much will left for anything.  I’m not sure I want to die but I just see any reason to live anymore.  If I had access to a cyanide pill I would take it right now.
