Only a pleasure! You'll be just fine! Looking at your photo, not knowing everything you've told us, I would say you look about 17... I would never put you younger than 16.
I think all the girls suggestions here are pretty much along the same lines... and you're right, you're almost 20, time for you to play around and find 'YOU'
I can say that only from about the age of 26, did I really 'find' myself but you're growing all the time... Enjoy it!
