I'll just say something to you...Even though you say Alan Walker is your life, I'm not stopping you, do what your heart tells you.All those silly people who don't understand that this is your life, and you can do what you want.Even if people make fun of you, does that mean what they say is true?What if someone out there is like you but is too afraid to show it?What if there's someone out there that would like to be your friend irl but is too shy because of all these people making fun of you?
You can say you want to kill yourself, but trust me, if you die do, you'll hurt all your loved ones that'll miss you.I will accept anyone as a friend, because we're all humans.Things like these issues can never replace a true person.They can say what they want, but you can show them you aren't a stupid person.At school you can prove that you're a human too, because you are, and no need to deny that.
Remember, we're here for you.
