There's no point in consistently worrying about everything. What will happen will happen regardless. So breath, look on the bright side. Have some laughs, fall in love, accept what you can't change, and carry on. To actually live is courageous.
"Hardships often prepare ordinary people for an extraordinary destiny." Move past your hardships and prepare for the good things that come afterwards. Don't let your hardships jade you or blind you to the greatness that life is offering.
