I moved from my hometown when i was 12, i am now 15 and trying to find a way to tell this girl and go back home

When i was 12, and barely starting my social life, my mom decided it was a good idea to start a moving spree and i was stripped of everything i knew, my life, friends, and special places. I met a girl who i am still deeply in love with. My main fear is that i never become a normal person (I'm pretty shy and feel like i didn't developed in a normal atmosphere). However, because of this solitude (I haven't made a single real friend, or got anything that ataches me to the places ive lived in) i have discovered my true self. Everytime i talk to this girl, i want to tell her how i feel but i restrain myself because it will go bad with a long distance relationship, as experienced through my brother's life. I really like this girl and i need to find a way to go back and tell her how i really feel about her
