I don't know exactly what you did, but you said that you were a tech kind of person, and that is a good thing to have in your vitae.
One thing that you might consider is working as a temp while you get your resume polished, get back into the work space, alter your routines into a new flow.
Having been on a work break for a considerable amount of time doesn't make you less valuable. I wouldn't expect to land right back where you were when you left, but you know that some skills are ever in demand, and your age doesn't mean that employers will not consider you. Don't let anyone discourage you. You did say that you are tenacious.
If you are good at interviewing, that will take you further into consideration, too.
