Broken toe or no, it is your continued physical resilience that leads to increased mental resilience. The clamour of solitude you describe in this is the same thing I experience when people cancel a photoshoot that is meticulously planned and the self doubts creep in.
It's not you. It's them. It is okay to be the main character, but to wonder why and what the motivations of all those other main characters are is natural as well.
I try to put myself in other people's shoes as much as I can as I feel like it makes me a more learned and compassionate, empathetic individual, but with size 14 feet, it's hard. Other people's shoes are far too tight.
