she is so lazy also...i get it from her. I think that im going to be pretty much screwed until i move out and get a job.
Sounds a little more like depression to me now.
Sorry to hear your mother's disabled, but you can't blame your own laziness on her- Whether she's lazy or not is her choice, you've still got a choice of your own. Sure, being around a lazy person can rub off on you, if you let it- Keep in mind, being disabled, maybe she's got reasons for not getting off her ass, and if that's not the case, also keep in mind that being disabled can be enough for most people to not want to get off their ass.
Still, you're not disabled. I don't know how old you are, but if you're old enough to do so, maybe you could find a job to buy the food you want. If you're not old enough yet, then maybe you can help her out with the food shopping, and make sure you ration some of it out for yourself with her consent so that you can eat right more often. Believe it or not, moving out might not be the answer you're waiting for anyway- It's like this guy I work with who says he's going to work on losing his gut when the weather gets warmer. For the past five years. The bottom line is, you can do something about your situation. Yes, it's going to take work. But that work is going to pay off, as long as you actually do something about it- I mean, you started the thread asking about motivation and looking for helpful advice- But when advice is given, you had excuses. We can help you out here to a certain extent, but we can't lift the weights for you- We can't send you meals, and we can't help it if you're lazy. Those things, you have to take care of yourself. I do guarantee you though- If you eat right, the energy will be there. Also- If, when you get home from school you go straight to your home gym and crank out a twenty or thirty minute workout, you'll feel a hell of a lot better. Trust me- Before you do anything else- Hit the weights when you get home. It'll wake you up some, you can sleep later, and once you get warmed up it'll feel great and you know it. The next day, it'll be easier to jump right on the weights, and before you know it, you're off and running.
