The bullshit you're fed your entire life has buried itself deep inside. Don't let this shit get to you. What others say isn't always true. They tell you you're worthless. Don't believe what they say. Everyone is worthless in some kind of way. You care for others but not yourself. Imagine your life through the eyes of someone else. You think you're dealt the hand that you deserve, but you don't deserve less then what you're worth. Blaming yourself won't answer questions when you ask "What's my purpose? Why am I living?" Fuck your doubt. If you believe in nothing else then at least believe in yourself.
