Changing my *legal* name

My name does not fit me in the slightest, I hate it on myself, I've never liked telling anyone what it is, and if someone knows my name without knowing what I look like it's heavily confusing given the name is more commonly found on girls of a different race (names obviously don't have a race, but it is one of those names you wouldn't expect someone of a certain race to have). I turn 18 soon, and I intend on changing my name ASAP, but I really need ideas/suggestions, any names that come to mind based off first glance of me, or that would actually fit me.
