I would also talk to career counselor to help with narrowing down your interests, market trends and the industries, and education options.
However, coming from the computer field, there are a lot of options and areas to go into from support, programming, teaching, managing, etc. across many industries that it can be applied.
It can be helpful to look into the professional organizations for each of these fields which are on top of the industry needs and where they are going to help you better curtail your studies to fit the market place, whichever field you choose or to help choose a field.
Many states also post studies on where they expect jobs to be in the next 5-10 years based on the population trends, needs, markets, etc. Look on the state government website for employment outlooks, which might help as well.
Once you decide 'profitability' and interest, before jumping full in, take a class or two in some of the things you might be interested in to see if it sparks your interest more or you may find the contrary. Job shadowing or informational interviewing is a valuable tool as well to know if you are interested and suited to a particular field.
I learned the hard way, just because there are jobs in something/very profitable and can do the the job, does not = happiness. Ideally find a combination of the two with interest and/or passion.
Good luck and so hope you are feeling better, take good care!
