You are in your 40s i still care what other people think of you you can't be happy joy can only come from living according to your expectation your purpose your life not other people expectation.
How can you spend your life up to 40 actually acting for people and still not be tired be yourself no matter what people say this is your only life on earth stop asking for people and start living for yourself start living for the people around you start living for how you want to find peace for yourself because only you can give yourself peace and no one can ever give yourself peace in the world.
That is how life has always been.
