IF she is a true friend, she'll listen without judgment and understand.
She'll be supportive and ask how can she help without getting on her soap box about people can be happy by choosing to be happy. It's much more than that...you know it, you're living with it, as many of us are.

We're struggling.

None of us choosing to be depressed, unhappy, sad...etc.

Wouldn't you love to be the person you were meant to be before everyone started telling you who you should be?
