For one to protect their mental health they must put up walls which are hard to penetrate. These walls must be sturdy so that when people throw verbal rocks at it the walls still stand strong. Mind walls must only allow information that one can handle to be leaked to those that have proven the are most trustworthy. Yet the inner wall must be the most secure for one must be protected against those they assumed they could “trust”. Even if a crack occurs you must have the tactics to quickly rebuilt because no person should be able to break you no matter what! Walls work not just with borders of a country but the mind as well.
