I've personally always felt rather protected from physical pain in life. There is always a way around it, and that may include prescription drugs. I don't fear dying in intense physical pain (like from cancer) because I know how many drugs are out there and I know opiods in particular knock out all my receptors. It doesn't take much. A tiny bit of a substance has a large effect. But it's also my mind. It finds a way to stop feeling physical pain when it's too intense. It's like one of the few secure feelings I have, that the world will hold me when I'm in physical pain, and it will save me from that pain. My psychological pain OTH has no savior. I must suffer constantly all day, every hour. That hurt is constant in my reality.
It's basically if I'm suffering physically "God" will come to save me. If I'm suffering psychologically I'm alone. No one, no god, no human can ever help. The darkness of the universe screams in my head, and I feel it. So all the people suffering inside psychologically, I feel for them too. We all hurt so much. And it breaks my heart. I want to save, but I can't even save myself, so I can't do anything but suffer as well.
