I'm not trying to sound like an ass, but if you are being bullied in any way, LEARN TO DEFEND YOURSELF! There's no need to be homeschooled just because some immature cigarettes are picking on you and ruining your life.
Get off the computer, quit complaining, and slowly get into shape in any way you can. Do push ups, watch what you eat, fap furiously, or just punch the richard in the face when they aren't expecting it. There is no reason to miss out on social interaction unless you really want to.
