17 but not year hasn't passed without trying to Learn To Sing.

Im 17, and ever since childhood I've been none stop singing. Though, I am a terrible singer. I have vibrato (to much sometimes) and can sing very high (not just head voice) ( I am a boy) I've been told by others that I just "speak the words" not sing them, and to "sing on the breath". I learned to breath more properly and been doing warm ups.

But what can I even do?

How can I learn to sing better, I wish to sing at church or somewhere, but my voice just isnt it.

(although my sister has been at singing competitions and almost won) My own mother has been at competitions and won, and my dad had his own very kinda popular rock band concerts. ( blood related aunt has won singing competition too) (and Uncle sings at church) I come from a very musical family.

I was wondering if anyone could possibly help me?
