Why me?

When we argue you tell me the truth no one wants to be my friend in the end they just want something and you dont want to be my wife you just want my money when we argue you tell me its over and i tell you so is my life you say good because no one loves you and i beleive its true because no one dont want me around i feel like a dog that need to be put down im full of anger and pain im just going insane so as i take my last breath i ask god why me as i put a bullet in my brain.
