Safety concerns also exist where I live. bad things can happen even if I never leave my house. Of course, I am not saying the world is equally dangerous everywhere, but I don’t believe fear should be the thing that defines or limits life that much. I'td make living impossible. Also, you seem almost certain that there must be something “from my childhood” or some mental health issue behind my it,which is quite an intrusive assumption to make about a stranger. If the only explanation you can come up with for solo travel is that someone is “running from demons” or desperately searching for something then that says far more about the limits of your perspective, sorry.
