When I was 15 I lost my sister. She was my best friend, she was my other parent. I just passed our 14 year anniversary in November of last year. I'm going to tell you something you don't want to hear, but understand its part of it. Its going to always hurt. Deal with it by talking to your parents, friends, teachers, even a preacher if you go to church (or even if you don't, if they're any good at their job I'm sure they wont' mind listening anyway). Deal with it by loving him, knowing he's always going to be there. He's not here the way you want him to be, but he's never going to leave you. I see my sister in my dreams and feel her around when life is hardest (and even happiest). He's there sweetheart. I'm so sorry for what you are going through. Unfortunately you never 'get over' losing a sibling, you just get through it. One day, one tear, one anger fit, and one laugh at a time. I'm not sure how this site works, but if you need to talk and it will let you email me please do so. I know exactly how you feel.
