phantom,

[B]You have GOALS, self confidence, know what you want (!!), get along with others[/B] & that's something!
On the flip side, you've identified self esteem as an area that needs attention, so you are aware of your strengths & weakness. Kudos to you!!! You have MOREe going for you than many with self esteem problems.

Tauren is right, wait until you're 18. if you can ..
That will even give you a little more time to plan! If (??!) you can work part-time, start to save a little from now (if possible). Living on your own in large cities can be brutal for the 'unprepared' & there are so many predators looking at 'profile minors' like yourself (unhappy w/problems at home, issues w/ parents).

Learn what you can, & PREPARE from now. The year will fly! But from your post, you will be fine!!
Good luck to you phantom!
