I Dont See A Point In Living Anymore :(

you don't have to give up,instead be strong and find a solution to your problem,if you have a older brother or tell your father/mom about it so who ever did this will repay....so he doesn't do it with anyone else...try to make friends even if they are not to your liking....one day you find someone who is like you then ypu can share everything....don't let yourself down...be brave instead of being in fear....tell someone you trust and who can teach that sob....it's not the end of the world!

Of course there is a reason to live.
Being sexually abused isn't your fault, it's the fault of the person whom chose to abuse you.
Most people get bullied at some time throughout their life, you will have to get used to it. I've had people bully me at school, they stopped when I tried to throw someone off a 2nd story balcony. I've had bosses at work bully me, but in the end, as long as you stand up to them they usually back off. Sometimes violence is the only option, but that's why self-defence laws exist.
As for having no friends, you can always make friends. There is always going to be someone you have something in common with. But then there will be the users also, but they aren't friends, just pond scum pretending to be human.
Your life HAS worth, don't ever let anyone tell you otherwise. Stand up for yourself, because if you don't, no one else will.
