i have no idea what your skills are, but...
1) buy rice, eggs, and chicken in bulk at a warehouse store. make fried rice out of this. it will save you money and make you full while also staying low on calories. also buy a good multivitamin to make up for whatever you don't have in your diet.
2) buy coffee. assuming you're an idiot, you probably can't find a job that pays 100K a year, so you will probably need to work 2 jobs that hopefully pay 40K a year. 2 full time jobs a day is exhausting and you'll need coffee to stay awake. coffee is bad for you, so maybe only take it every other day. do take 1 day off per week
3) to make up for whatever money you still need, you can make some passive income by buying super cheap things at clearance stores or online and then resell them on sites like ebay or craigslist.
do keep in mind that you need to pay tax, so good luck with that.
