Yes life is too short to live without true happiness and purpose. Therefore, it should be our mission to seek out the truth about Jehovah's Kingdom. Knowing the truth and being a faithful servant of God brings peace now and forever!
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.
