Lost Young

My heart has been broken at a very young age.I am 18 now and it should not make sense but it still hurts sometimes.I haven't had a relationship since then because i was too scared.I didn't have the courage to approach a girl since then.Even if I do then I find it very difficult to tell my real feelings.Recently there was this girl whom I liked a lot but we are still just friends and she is dating my best friend.It hurts like hell but I never told the girl how I felt in fear of loosing any friendship that I have with her.I know I am too young for feelings like heartbreak but I know how it feels.I have no idea how to carry my love life forward as there is no 'love' in my life.
