It is true; no one in this world cares for you except ALLAH.
BUT ONE THING YOU SHOULD KNOW. You are the main caretaker of yourself. Everyone is busy in his own life, and no one has time to hear your problems. Whatever problems you face, you only have to solve them.
But don't get disgusted. Almighty is here, who is the caretaker of all the creatures on this earth, nay, in this universe. So place your problems only before HIM. Ask help with HIM. Flow your tears only before HIM. When all the human beings are sleeping in the night, you stand up before Him and ask for His help. You sob and cry and ask pardon for your sins and then ask HIS help. You will find a new beginning in your life. Do it every now and then and, God willing,
