Thoughts on my name - Kaylie?

I know this doesnt have to do with namimg a new baby, but this is the only place I felt was best for name advice.
M name is [name_f]Kaylie[/name_f]. I have recently come to the conclusion that I don’t like the name I was given by my parents. In my opinion, it sounds extremely childlike. Hearing friends and family call me this has become irrritating. I don’t feel the name suits me at all and it makes me feel extremely immature. I am constantly pegged with the nickname ‘KK’ which doesn’t make things any better, and no one can ever spell my full name correctly. I personally don’t feel I could grow up into a name like this. I am looking for honest opinions and I value all responses.

Thank you!
