Suicidal now

My lost client is burning me bad, I submitted a termination invoice and they are not going to payit.  Four years of good work and faithful work, but they can fire me in one day without even warning of the change.  I am tired of doing good for people and eating shit.  My monetary career is dead, I am so broke is not funny so once again I am pounding my chest to bring on a heart attack and just die.  My mood is horrible and I am suicidal.  I have no more wish to live and wish I had not been born at all.
