'Do not regret getting older. It's a privilege denied to many.' - It absolutely is a privilege denied to many. I've seen far too many amazing people denied the beauty of getting old with loved ones, so I will relish and take every birthday I am given.
Just hang on for tomorrow. Just because today is a terrible day doesn't mean tomorrow won't be THE BEST DAY OF YOUR LIFE. You Just gotta get there. Hebrews Jesus who is the same God forever, will NEVER forsake you, no matter how you feel.
