Are you the "child" to be supported, or is your mother helping you support a child whom you gave birth to? Your reference to the "child support card" wasn't clear. Either way, if you can possibly stay in high school until you graduate, that diploma will be your entry to many, many better jobs than you could get without one. The tone of your letter shows that you're not yet ready to go out into the wide world by yourself. Be glad for the food, clothing, and shelter you get by living with your mom. Don't try to grab every buck you can from her. Make plans for a decent permanent future, and work toward that. Yeah, yeah, it sounds dreary and so far into the future that it's almost impossible to imagine. But picture where you want to be four or five years from now, and figure out the most effective ways to get there. Otherwise you'll just stay stuck in the unpleasant situation you're in right now, because the one and only person who's going to wave a magic wand and get you out of it is -- yourself. This answer won't get chosen as "Best", because it sounds cold-hearted. But read it anyway, and think it over.
