Help How to drowning

[MapleS]

I don't have other method avaible. Please don't say it's painfull. I know that.

So the plan is to go to the lakw at night when the Ice will be there and jump on it until it shutters and I will drown.
One lake is pretty deep but exposed to eyes of people and one is shallow but there are a lot less eyes

Any ideas how to do it correctly? How to make my chances bigger?
And how to minimalise the chance being seen?

shallow water blackout, hyperventilate before going under to flush the CO2 out of your lungs and try to stay underwater until you black out, or take benzos and alcohol if available.
