Hurt by my friends..?

I know how you feel. There isn't much you can do really, just leg it out until the end of your A Levels. Don't let this get you down. Focus on your school work, instead of sociallising. Your teachers may have already said this, but, these are important years- the most important, you can have friends after. The A Levels are the hardest exams you will have to do- more so than Uni. Just focus on your school work, don't try to hang out with the others- if they want to hang out with you, then they can hang with you.
