Sup, sooner I'll kill myself

I'm some 15 y.o. guy who will kill himself (it's matter of time, not of choice). So... Does anyone have best method and tips how to suicide? I only know, that either drink a lot of alcohol or energy drinks for courage to die. I didn't plan exact date, cuz I need to leave everyone a suicide note (I have a lot of people around me, whom I really love and want to leave comforting messages)

If you care, I'm Christian Protestant (don't hate other denominations tho, can't understand this war). Love to play... Mhm... For example Space Station 14 lol.

Also, my life for myself is quite terrible, unbearable and I know that I'm disappointment. So I don't need some motivation or "don't do it". Because it's not on perspective, but life itself. My family is veeery toxic, neglecting and absent emotionally from my life. I live in Kyrgyzstan, where mental health is on poor level

I'm free to talk, discuss and react. Jesus loves y'all. Life is BEAUTIFUL and WORTH living, but not for me. Okay?
