I know how you feel, i was bullied a bit, but if you stand up to them they back off, they're only able to bully people if they know they can get to you.
You should get to know more people on here, all the ones on my list are really nice.
But you can always talk to me, if you don't feel comfortble enough sending out more friend requests, if you decide you want to get to know more people, i'll see if some of them will send you a request.
