yellowfree,
I want to tell you I empathize with you. My family was too poor to put me through college, though my Father insisted he could have found a way. I joined the Navy and served my time, in the process earning the GI Bill. This is paying my college expenses. I am not so much older than you and my last hourly job paid $9.80. It's hard, but I've never been able to push myself to do what I didn't want to.
My grandmother once told me my father and I are both disappointments to her because we did not attend medical school, law school, or even dental school. My mother told me she doesn't understand why I majored in Christian theology. But, I told her I have free money from the GI Bill and I will study what interests me. I once served an apprenticeship and learned a trade but I haven't actually worked at it for seven years and I have found it difficult to get back into, though I liked it.
Conclusion: We live in a difficult economy and contentedness may be something you need to learn apart from money. Don't force yourself to travel a path you don't want to follow.
