I think the test of really really wanting to die for reals is to go parachuting. Jump out of a plane and make the decision if you'll use the parachute or free fall to the ground. If you use the parachute, then you really want to live. Seems to be cheaper than a $40K pod.
If you really want to end yourself, you will find a way. It really is not that hard. Its amazing how many humans live to old age. Humans used to die if you got a stubbed toe and it got infected.. When you were otherwise young and healthy.
Or if you have a death wish and wont do it yourself just dress up like a super hero and go into the gang-banger areas of any major blue city with a baseball bat and go after the criminals. You will last all of a minute.
My mom has a suicide kit in her closet. Helium and a plastic bag. She has said she never wants to become a burden and if we find her on her bed with the plastic bag and tank we will understand that she was ready to go on her terms. She has made sure that both my brother and I have access to everything and apparently I'm her executer because I didn't get the jab and have a copy of her will in my safe.
That is rough. Just knowing you are in that state of mind in a way is probably calming but still. Having your family know and understand is hard to handle and I am not close with my family.
