Do you have someone around you, who is not talking to you?
You’ve tried everything, yet there happens to be some mystery?
I came across this quote of Tony Robbins, that would help:
“The unhappy person resents it when you try to cheer him up, because that means he has to stop dwelling on himself and start paying attention to the universe. Unhappiness is the ultimate form of self-indulgence.” – Tony Robbins
Read that again. And again.
And then, bless them. And move on!
