Most of the human population lives conditionally. In other words, the conditions around them dictate how they feel. When you care about what others think, you are trying to control a condition that you can’t control. You will NEVER be able to control what others think. So stop trying. Stop caring about it.
The only thing you can control is how you feel and react. Therein lies your power. When you are attached to what others think, you enslave yourself to them. Give it up. Turn your focus on what you want your life to look like. Contemplate you space on this planet. What value can you add to the world? Then make that your ultimate target.
