Help Is CO method possible while being constantly monitored?

[YourLocalSadGirly]

To my knowledge to make CO work you need like 1.5-2 hours to let the smoke burn off to make sure you die from CO buildup and not smoke inhalation. Problem is that my parents are constantly monitoring me to make sure I don't die. I've thought about hanging but I don't want to end up with brain damage from a failed attempt or being found. My current idea is to drive somewhere secluded in the middle of the night to do everything. Does anyone have any ideas where I could park in the middle of the night and not be bothered for around 2 hours?

I don't want to go to a campground because of the high likelihood of being found early and also I don't want to scar random people who find me. Other ideas besides parking somewhere are also welcome. I've been thinking about this for awhile and it seems to me like this method might not work out for me unfortunately so I'm asking here as kinda a last resort lol.

Im also concidering CTB in my car late at night but with inert gas method. Im considering parking at a near by forest or a near by beach. Sombody is going to have to find me anyway and i prefer it is not my family but rather the police. Inert gas requires less preperation and no risk of fire so i can attempt at a forest, its just spooky and rase my anxiety levels. The beach on the other side has police patrols from time to time and might stop me and save me.
