Aside from the great general advice you are getting here:
You can always go back to school or learn a new trade. The only thing preventing you is "being in competition" (your words) with people who have more experience.
Don't compare yourself to people who have more experience. For example, if I were to pick up Computer Science today (late 30s) I would be happy to compare myself to 20-somethings who have a similar level of experience.
Of course, I have more life experience, hence other skills and perspective, and that is enough for me.
"You can always go back to school or learn a new trade"
Whoa, isn't that a little flip? Depending on one's life situation, it can be impossible to do those things. They require time and money, two things people may not always have - particularly if one has children, a mortgage, etc.
