You have no idea what lies beyond the reach of your senses. You have no idea what comes after death. Don't believe some self defeating story you completely made up based on nothing, that's like punching yourself in the face for no reason.
The events of your life don't drive your mindset directly, that's why you multiple people doing the same thing can each have wildly different perspectives. You ultimately decide how things affect you. You are the only one that can reach the deepest parts of yourself.
I can tell you don't workout, because the pain that comes from lifting makes any pain of existential dread seem like child's play. In a lot of ways it makes any women trouble seem like child's play too.
The ego is funny when it's main complaint is lack of immortality. Who is to say we aren't immortal? We have no idea whatsoever. And if we aren't, better to face oblivion head on, sliding into the grave, than cowering in fear or anxiety.
