help budgeting (please!)

Charmed285

I need help with budgeting money because I don't know how to shop, I never know what to buy or how much to spend. I don't have kids but I live with my parent's who don't eat healthy but since they can't afford much food either and only once a month I want to buy enough for all of us if possible. healthy food that is to last two weeks or longer if possible.

the most I will ever make at my job (making 7.25/hr min wage) is 400.00 every two weeks, however, I may not always get that amount. I have bills to pay like my internet which is about 80.00, phone bill which is 112.00( unlimited everthing and wifi hot spot with 2 other people on the line) and for public transportation which is 120 a month (30/week). plus the cost of tutoring and gas to get back and forth. the way I see it I can't afford food, let alone healthy food and the only place I can shop that is near me is walmart and food lion, unless I travel 30mins to an hour away to another town. I'm told I need to cut things out but there's nothing to cut I need them all.

what do you think? can you help, or is it a loss cause?
