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.
Jealousy comes from counting others' blessings instead of our own. So very true, don't let your life pass by while you worry about someone else, count your blessings, be grateful, be happy for others (even though it can be hard).
