Think about every good thing in your life right now. Free yourself of worrying. Let go of the anxiety, breathe. Stay positive, all is well.
Never give up. Things may be hard, but if you quit trying they'll never get better. Stop worrying and start trusting God. It will be worth it.
Don't you ever think that your mind can never harm you just because it is your mind! Your mind can really kill you. From dawn to the time you retire, your mind can be a very good friend to you and your mind can also be your worst friend. What goes into your mind each day becomes your friend so mind your mind!
