well you could try offering them some cash money,,,,,
Get out of your comfort zone be outgoing and open minded just be yourself really :)
Keep doing the things you enjoy. Soon, people will notice you and your talent will open doors to new friendships. Try also getting involved in new interests/hobbies. It will take a some time, I'm sorry to say, but once you have the first few genuine laughs with someone, you'll find you have a new friend. ;-) Best wishes with the new school.
