Lisa,
You know I'm not a newbie, but I'll comment anyway.
You said "I don't give a crap who likes me or not" was a lesson that took me too long to learn. For decades, even as a brother with responsibilities, I was too easily upset when fellow elders who disapproved of my decisions (sent my wife to college, helped in home births, home schooled our kids). I finally adopted a philosophy, "I don't give a damn".
A few years ago my daughter got a navel ring and gossip went all over the circuit and district, even to near by states, though no one had really seen this navel ring. She was upset, I was under the gun, but I tried to teach her "I don't give a damn". Like me, she was too dependant on the approval of others.
Now we are all fading and really don't 'give a damn'. But I admit that is conditional. We all have people in our lives we care about and we do not want to disturb them. For those we love, we give a damn. But all those small minded, self righteous fundamentalists we used to live with can just take a hike.
