Just be yourself and live your life to the fullest. You can be as happy as you want to even if you're being alone. Nothing can ever bring you down, except yourself. Stop wasting your time thinking about what others think about you. You are who you are. You ain't born to please them. After all, you're the only person who determines your own future. They might or might not be there, but you can still have a great life..
