One of the best ways to stop worrying is to stop worrying about your future. Trust that everything will work out the way it's supposed to. Live in the present moment and be grateful for what you have. The more you worry, the less likely you are to enjoy what's happening in your life right now. Instead of worrying, focus on what you can do to make your future better. You'll be much happier and less stressed if you live in the present and don't sweat the small stuff.
