Thanks for writing in
Reading your letter it seems you think that no one likes you because you are boring and quiet. Because of this you find it hard to make friends. You say that you think people are turning against you.
It's not always easy to make friends, but it does help and makes life easier to mix with others that we have the same interests in though.
That means that you can choose to be around people that you like, and know they like the same things.
Friends are people who we want to be around because we like them and can get on with. So could it be that you just don't have anything in common with these people?
Is there someone that you do get on with? Maybe ask them why do they think people are ignoring you.
There must be others in your class at school or college who you like and can find out whether you share the same interests.
Have a look at the ChildLine message boards and try posting a message to see what others think.
Good luck
