least painful suicide methods

(16)m im in high school still, i get okay grades my dad knows ill never get straight 90s and 100s in my classes but hes still always on my case about doing good, i have ADHD its really hard to focus and my parents dont let me do anything other then go to school and come straight home. My stepmom is a real problem, she knows i cant handle anger that well and she takes advantage of me by verbally abusing me until i either crashout or just start crying because its hard to just thug it out, shes a bully until i do something back and she acts like shes the victim, she tells everyone how much of a demon i am but its the complete opposite, im really close with god and i believe heaven and hell is real thsts why i dont know if suicide is an option because its a sin, so i find myself praying for God to take me in my sleep but honestly hell might be a better place to be than right now, i have alot of friends and family that love me but i forgot about everything when im in this house because ill be having a great day then i come home and im immediately in a suicidal mood, ive bern feeling like this since i was 11 and i never told anyone because my dad gets mad whenever im sad because i have “no reason to be depressed” but i know i cant not be depressed with how im feeling, but i dont wanna feel like this anymore i just wanna die so bad, i even tried running away but even that my dad wont let me do, i remember that day perfectly because it wasn’t that long ago maybe a month, i was sitting on my bed thinking and i said to myself fuck this bullshit im done with it and i started to take everything out of my book bag and fill it with clothes, it was a janspott bag so i couldn’t fit that much in there, i went to school still but i didn’t do anything and i skipped my last two classes with my friends that i was gonna be staying with, my dad started to blow up my phone talking about “after everything youre gonna do this to me” i wasnt the first son of his to run away my two older brothers 23 and 24 ran away when they were my age, but i ignored everything my dad was saying and then he found me right as i was about to cross the street and leave and he made me go back to that broken household, now here i am just waiting for God to let me die in my sleep but im getting tired of waiting and i wanna do it now, i didn’t mean to tell you guys my life story(not even close to my life story) but i came here to ask for help with painless ways i can kill myself, dont bother telling me not to do it because im too young because its happening one way or another. but yeah give me some ways pls im begging
