New school year

I've started junior year and so far it's going alright i made a ton of new friends but there's this one that won't leave me alone. He's very anti-social and has anxiety and new to the school and doesnt have any friends but me. The issue is hes very and i mean very clingy he follows me everywhere and always is looking for me to the point i find it creepy. i want him to find new freinds in order for him to leave me alone for a little bit. idk what to do tho.
