I have a narcissistic personality disorder, what can I do?

I am an alcoholic that has been sober for over a year now. My family and friends have noticed that once the booze was gone I exhibited a personality disorder. So now I'm a recovering alcoholic with a narcissistic personality disorder and I want the best for my family. My wife is pregnant and we have a 2 year old girl. Staying sober is tough, but overcoming this narcissism is impossible.
