If finances are an issue, don't let that keep you from getting the help you need. Check with your public library since some offer career planning help. Also check with local colleges and universities. Most have career development offices which may offer services to members of the community. Programs that train career counselors often have students work with members of the community in order to gain experience. There are self assessment tools you can use for free online.
What you should end up with is a list of suitable careers based on your self assessment. Obviously you can't do everything on your list, nor will you want to. Here's where you need to do some research. You should begin to gather information about these careers which will include a job description, outlook for the field (will you be able to find a job), and required training and education. When you have narrowed down your choices to just a few, then you should investigate even further, perhaps conducting some informational interviews with those working in the field. You can now make an educated decision about what career to pursue.
