It sounds like a riser bar would be the next logical step for you, but you may be better off getting a fitting before you do anything. Does the shop where you got the bike offer that service? If not, check any of your other local shops. It'll cost you, but it's money well spent IMO.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
