Don't feel like a burden to others. There are always people who care about you! Don't feel sad, you have a place in this world. You are perfect just the way you are! We all have some flaws, sure, but why in the WORLD would existence allow somebody to be nothing but trash? Well, guess what: you are beautiful, perfect, and amazing just the way you are. Remember: You are important, even if you feel like nothing but the smallest grain of sand in this large, empty and dark universe, you still have a place here, a place in people's hearts. You matter, and are nowhere near "the worst" (P.S: there's no such thing as a horrible person)
