Help!Scared to cut my hair!

Ok, when I was like 11, I had hair down to my chest.And I was real daring so my friend and I went to go get our hair cut together.I wanted to go really short but I chickened out, and my friend rachel, got hers cut but it was already short.As I was getting my hair cut I was real nervous.And after it was cut, it was alittle bit shorter then jaw length.It was the worst hair cut ever!!!!!!!!!!!!!!!!! I freaked and hardly cut my hair again. But now Im 15, And I lost a ton of baby fat.And my hair is now blonde and cut to my sholders.But ever sence that hair cut/ the short ugly one/Im scared to get my hair cut short. But now im older and Im thinking that im more grown, and im willing and thinking about getting my hair cut short, like chin or shorter in the back, or layered short. Please help.I want to look my age, not to old but sexy fun and cute. Im thinking about doing what my friend Jane did. She just went into the bathroom and cut her own hair. she went from butt length to chin. In about 5 min. should I???????

try style 4600 on this site(style selector) it will be shorter than you have but long enough to be able to still do different stuff with your hair ,just have a look ...it is your choice ...but hey cut it go on it will grow back if you dont like it coz you are only 15 take a risk..try something new..you dont have to get it styled to short to start with.. and then if you want it shorter get it cut shorter after a week or two..bye
