The sunk cost fallacy is a very easy way to get stuck being miserable.

Sometimes a drastic change might be painful at the time but will be much better for you overall.

The quote. “Resentment is like drinking poison and expecting the other person to die”

It’s like you’re doubling down on what happened. Either they didn’t know/care it hurt at the time or wanted to hurt you but now you’re using your energy to extend the hurt.

When you start getting angry about it acknowledge it but then do something positive for yourself.

Thou shalt spell the word “Pheonix” P-H-E-O-N-I-X, not P-H-O-E-N-I-X, regardless of what the Oxford English Dictionary tells you.
