Hi. You have an old mindset...

today people aren't worried about college degrees much and the government is pushing tech schools instead... I won't go into why I think they are doing that.. but why not "just" go get your GED?
If you wish to go further, see if you can CLEP or test out of college courses that have information you already know? Some colleges charge the full tuition rate, but you won't have to attend class and waste your time with ignorant professors.
But you can always take certification programs instead too...if you need that wall paper (and I agree, it's nice to have to show for a boost in job at times).
I think you were bored in school...and only wanted to study one subject... You know Einstein has issues with some subjects too? (And he only had about 5 hours a day where he could think like a genius!)
Anyway... go get the GED and then you can see where you wish to go from there... I mean, man, it's a test you can probably pass...or buy the book and learn the answers....
Don't base your whole life's future on the garbage from the past. We all were growing up and learning how to live then...more often than not we learned from our mistakes! Today is a new day...and so is tomorrow...what would you like to do with it? Go for it!
