Well if you are 22 and thinking of leaving parents house the best thing is to wait until you have at least a college degree or talented in a skill. However if you still insist on leaving there are areas that you can find ready work even without attending college. Sharpen your computer skills there are lots of jobs in the tech fields. Another area is the construction sector. Restaurants, shops are always hiring. You could get a job. Contacting an employer you have already worked for is a good idea. Behave normally when looking for a job but beg only as a last resort. You could get a gym membership to clean up and get warm during winter.
