To wonder if it's possible to run away from it all and just live a quiet life with no one else to rely on

[HealthRobinsonCrusoe]

Or is it intolerably hard as I need to just knock down

Well do you have children? A bit more detail may help

I suppose it's possible yes

But you'll still be carrying whatever it is in your mind unless it's a person or people you want to get away from

Are you ok OP? What's going on ?

Yes, of course it's possible! How to do it (or whether to do it) depends entirely on your situation. What's occurring?

I think I live my life without relying on anyone. So that's possible. Whether you can run away probably depends on whether you have anyone relying on you.
