I Want to die

I have no reason to live any more I hate my life all I do is cause others around me pain. I never smile and when I do it is fake. I figure it will all be easier for everyone for me to just die, no one will care and when I die I wont care either. I have thought about it before but never managed it. I know I will miss things I love like reading and anime but I also know that when I die I wont care any more. All I want is a quick painless way to die, I have no access to a gun and I don’t want to wuss out any way please help me.
