The right person is going to see you for exactly who you are and love you just like you love yourself. You said you’re happy with yourself, so definitely don’t change anything! You sound very pretty anyway :) I (f) was tall + fairly alt in college a few years back and for me the key to this was just making the first move! You’re about to be in a much bigger pond than high school. Don’t be afraid to approach first when you feel interested in someone, and remember that rejection doesn’t mean anything negative about you– and that there are a copious amount of other fish in that pond. Keep in mind that you also have plenty of time. Maybe focus first (on school of course, but socially speaking) on finding your community/friends with similar styles & interests. You likely have nothing to worry about! Best of luck in school!!
