How to kill yourself painlessly ?

Im 16 & im not at all scared of death.Im just scared of the pain.

P.S-i dont need anyones advice on how precious life is an any such shitty advices on how I should see a counsellor or talk with my parents.I got enough problems like-

•my parents think I gave them a bad reputation and wish they never had me.

•i was an A grader but now i have already failed in 2 subjects this term

•My parents wont send me abroad

•Only some ppl think im pretty so I cant be a model.

•I already suffer from depression and anorexia.

And if anyone feels on how I should think about ppl dying in syria and should value my life,no need to comment.Let them die,idc.

I just want methods on how I can kill myself painlessly.And ideas on how my death shd appear as a murder.I want to get many ppl in trouble.These methods should be easy and not complicated.

Im not seeking any attention.If I wanted attention I would have asked this on Facebook.

**** society and this shitty education system.

Do post links about easy methods.
