Help!? i am feeling really alone and lost!

I have always had lots of friends in school and i have always been the person to put others needs before mine, sometimes its bad but i am always there for my friends! my best friend had anorexia and she ran away earlier in the year, i tried so much to find her. though when she returned she and my group of friends made up tons of rumors about me. i moved friendship groups, i sat with them for a few weeks until they turned on me. i then started to hang out with a friend since primary school, it was going good until she made new friends with a group who bitch about people all the time! i have ran out of options on where to go because i don't want too talk behind peoples backs, sit with people who hate me, or sit with the 'cool kids' because all they enjoy talking about is sex and be mean to people. for the past few weeks i have sat on my own in the classroom, i tried convincing my parents to let me change school but they keep saying no because apparently i need to get stronger and fight through this, they said i am judgmental and putting myself on a pedestal and think i am above everyone else which i am not. I don't know what to do! i have no friends left at school, i go to an all girls school and my only friends are boys from the all boys school. i get along with boys so much better and that's why i tried to convince my parents on moving me to a co ed school. helllllllppp please!!!!
