Music has the power to soothe, to calm, to encourage introspection, to heal. If you want to feel good and "hol' a vibe" then putting on some music and dancing like no one is watching is definitely the way to go!
Children don't belong to their parents. "They are the son's and daughter's of Life's longing for itself. Though they may come through you and are with you; they don't belong to you. Don't give them your thoughts for they have their own." Khalil Gibran
Worrying is unhelpful and a wasted effort. The energy, effort and attention we pay to an issue that may or may not come to pass is truly wasted and is a sure way we rob ourselves of that precious peace of mind. It might not always be easy; but try to remember there is a solution to every problem you just have to find it.
