Where can you get rope that is sturdy enough for a 6'6 250 lbs man
If I'm going to commit suicide (I never would though, this is more about preference), I say take the scenic route, google the tallest building in your country, spend the entire week leading up doing the things you enjoy, watch porn, eat your self full with your favourite foods (being fat doesn't matter anymore), play video games, etc. Get your affairs in order ahead of time (wills, debts, etc), this will have to be done days or weeks before.
Then when its bright and sunny or darl and gloomy, whichever you prefer, get to the top of that building and jump off. The impact will likely kill you instantly (so no pain) unless you live in a really shit country where the buildings can barely be called "tall".
I don't think people realize how painful and torturous suicide by hanging is, your body is actively struggling against your death, you'll feel yourself choking and suffocating, sometimes your body will even expel fluids and excrement due to the panic, adding a whole other layer of unpleasantness to your death.
Don't kill yourself, but definitely don't hang yourself if you are going to kill yourself. Jumping off of a building also has the added "final troll" of making normies witness something gruesome and they have to clean up your body parts and guts spread all over. If you are lucky you might fall on a normie and take them with you, it is truly the best kind of suicide.
