Feeling lonely and feeling like a freak compared to everyone else

Feeling lonely and feeling like a freak compared to everyone else High School has been very difficult. I've had no relationships. I've had so called friends who only interact with me for answers, or if they need help with a question. I sit by myself during lunch, and don't talk to anyone, I'm your classic loner. I've been wondering all my life, "why do I deserve this?". I feel like such a freak, the abnormal kid. The weirdo loser nerd. Some people in my classes don't even know that I exist! Everytime I'll try to talk, these assholes would snicker, mock, or ignore me. It makes me so angry, and so sad. Thanks for reading my vent :/
