I remember when I blew into Seattle looking for a job many moons ago-- it took a lot of pavement pounding and a lot of rejections but I did find eventually what I was looking for. Several suggestions:
1. You need to get a survival job-- any job from flipping burgers to spilling coffee at Starbucks. Its always easier to find a job when you already have one.
2. You need to further your education somehow either by practical means or scholarly pursuits. A high school level education is only the beginning of your life's pursuits.
3. Think about doing yard work for people. I remember that when I was going to college in Bellingham I started doing elementary lawn mowing and lawn maintenance for homeowners and I had more work than I could handle.
4. Do some volunteer work which often leads to gainful employment.
5. Join the military.
6. Marry Bill Gates' daughter
6. Good Luck
