I am sorry that you've fallen into such sadness over your life situation. What I can remind you of, even as I lack my own experience in work and true maturity, for I am still in my youth, some years younger than you, is to not fall into utter despair over all of the struggles you're facing, because there's a savior above who loves you and who wants you to triumph over the toils of the world that its evil state has given us. It won't ever be over until The Lord says so, and right now, His hand may be hovering over that clock, but it ain't touching it, and He knows when He'll stop it, but we don't, and so we must continue to struggle for Him, in part through seeking out labor and working through it, in spite of the aggravation such a challenge will cause us. Let your tears fall to The Lord's hands, and let them grip yours, and help you up. You will find joy in this life, and success, and prosperity, and peace, through this persistent, ever-burning faith in Him.
