I'm 48 and only just making the realisations you're making. Well done for getting there so early!
My biggest takeaway of the last 12 months' personal evolution is the following:
I don't need to be liked by anyone. In fact, I get to choose if I like THEM.
This has made social interactions SO much easier and more authentic (and therefore less exhausting).
You are totally on the right path... keep walking!
