You need to calm down with begging for answers. Not everyone lives on here all day. Some people have lives, jobs, and families to attend to now and then. It might also help if you tell us what vehicle this is.
With the engine running, check the voltage at the battery. It should be hovering around 13.5 to 14.5. If it is anything less, the alternator is not charging. This could be a problem with the alternator or the fusible link that connects the alternator output to the electrical system.
Your battery is toast. Buy a new one. You don't kill it or drain it that much without wrecking it. Buy a new one regardless.
