Approaching women..

Approaching women.. Guys, I am 29 M. Have been stuttering since I was 5. Every time I approach women I stutter, and they think that I am not confident or something and they immediately lose interest in continuing the conversation. Today, was another failure for me. I tried to talk to this girl that I like, and I wanted to introduce myself and could not say a damn word, and she looked at me like I was crazy. Every time I approach someone, I always fail. Meaning, I can clearly tell by their facial expression that they are confused. After that, I don't have any interest in approaching people again, because I know it will put me down and just ruin the rest of my day. How do you guys approach women? Any decent advice you can share/give?
