How would I go about fixing my smile? I really can't afford to pay to get my smile fixed because I am a mother of two. (photo)

I have all my life had really bad teeth and I've never been able to talk around many people that I don't know personally. I have gotten to the point were I am ashamed to smile in front or anyone. I am ashamed to talk to anyone because I feel like they are looking at my teeth and not me. I love to smile! I love it ! I don't want this to have to be the rest of my life being ashamed and afraid to open my mouth around people because all they are looking at are my bad teeth.
