People who were happy and in love, are not, but they are.
People who were happy at home must party.
People who had it all, suddenly want none of it.
This is not about you so don't let the world turn you inside out or upside down. Don't try to think how you could have avoided January becoming December, or your H losing his direction in life.
You must keep your sense of self above all else, and let those that can help, reach out to you.
