Tell me how old i am really?

Firstly you have not actually stated how old you actually are. But age is always on the increase and though you feel you should be 15 it will not be long before you are. Also there will come a time you will look back and wish you were 15 again. Age is a state of mind I am old but I feel young you have a long life ahead of you. Take each day as it comes and be grateful for it.
