Freewriting your thoughts is a powerful way to get a handle on what you're experiencing. Sharing them out loud is the biggest and most important step.
Apologies are not required!
Take time for yourself, sit and ponder but always have your friends and family either by your side or just a phone call away.
Work out what is troubling you and deal with it. The only certainty is it will pass and everything in life is temporary!
Be yourself and be nice to yourself because you deserve it :-)
