When I was 21 I tried to do what you tried to do here, and I ended up living with my sister with -$83 in the bank by the time it was all said and done. I am 24 now and doing much better in life, but it was a long road to get here. I can promise you that it will get better, but you will have to work for it.
My suggestions:
- Start filling out applications for any and every job. Get a job. It doesn't matter if it's cleaning toilets or flipping burgers. Right now there are people with PHD's who are riding on the back of a garbage truck. Put your pride and passions behind you, and take any job you can get.
- Until you get that job, do anything you can to get money. Go door to door with a lawn mower and cut grass. Troll the free section on craigslist and find a way to sell the items listed there. Walk into the small mom and pop shops in your area and ask if they need any help involving IT whether it be building a website, designing a flyer, setting up a wireless network, fixing a computer, anything. Ask if you can leave your number with them if anything should come up in the future.
There's always a way to make a few extra dollars, and you'd be surprised how much small businesses are willing to help out someone down on their luck who actually wants to work. Swallow your pride, get out of the house, and get face to face with people who have succeeded where you have failed.
Best of luck to you.
