Your mind has very little control over this world. It is neither omniscient nor omnipotent. It cannot control the weather and other natural forces. Nor can it control all people, places, and things around you. You have given your mind an impossible task by asking it to manipulate the world in order to fix your personal inner problems.
If you want to achieve a healthy state of being, stop asking your mind to do this. Just relieve your mind of the job of making sure that everyone and everything will be the way you need them to be so that you can feel better inside.

The philosophy of Stoicism instructs that in all things you should first determine if something is within you control. If it is do something about as needed. If it is not then don’t waste any more thoughts trying to solve it.
Stoicism also instructs to accept, welcome, and appreciate everything that happens, not assign good or bad to them, and just accept them as what they are .. just a thing that is neither good or bad. Just part of your movie reel of life that has gotten you to where you currently are.
