Awww ponine thats horrible! We love you and want you to be happy! You are a funny, smart, pretty, sweet, and mucho talented young woman. Just give it time, eventually A) Those girls will realize how totally wrong they were and apologize for being such bitches or B) You will find someone who is in your same boat and end up really good friends
As for lunch, yea sitting alone sucks. Most people aren't going to come and ask you to sit with them, sadly it doesn't work that way. Just look around, see any potential friends? Ask if you can sit with them... From the sounds of things, the only way to go it up
