Help methods that are both easily cleaned up and highly effective?

[settling]

so my original method was originally a shotgun (99% success rate) but then i realized that clean up would kinda suck. my plan was strategically wait until a time when my mom left for a reasonably long while, call the cops to ask them to pick up my body and then blow my head off, so that the chance of my mom seeing my body was low. but even then i thought about like when my mom would go in my room and smell blood and stuff later on. and not to mention idk how long and hard it is to clean that scene up.. so im looking for other options, but it seems every other method sucks. i dont wanna do hanging because my rooms ceiling is not that high up and it also seems like a fucking nightmare with what people here say. drugs seem pretty ineffective from the stuff i hear here.. (fentanyl maybe?)
please be highly effective i dont want to wake up in the fucking ward and have my constitutional rights taken away because my life is a fucking nightmare and i tried to escape it
buying equipment for an exit bag seems hard also
should i try the modus operandi of this site? (SN)

i have $475 to my name rn if that matters

I can't provide advice but read your post and sorry things feel so bad. You sound possibly young. Have you tried to get better at all?
I think she'll be traumatized no matter what, but yes, finding your body and blood may cause PTSD. Losing a child to suicide is devestating and life altering in a horrible way no matter what, however.

Can I ask the reason you are here? Sorry if the question is overly personal.
