You're not broken. Your best days are not over. You aren't a shadow of your former self.
You're just in transition.
You're shedding your skin.
And you can't yet see the one yet.
But don't worry. It's forming. It just needs time to reveal itself.
Transformations are a bumpy and dicey process. Don't let anyone tell you otherwise.
Hang in there... the good part has yet to come.
