I have a comparable story; dropped out of school at 15 and didn't touch education since (>15 years ago now), then spent a few years high and drunk: but I'd learnt perl from the camel even before then.
What do you think you are owed? If i hadn't read k&r or learning perl by myself I should then blame my teachers who hadn't read them either? Most of the best folk I've worked with found these things on their own too.
You feel you're "a lost diamond that the system left behind?"
Bitch, who are you blaming here? The only job I could get in that situation was as a cleaner, and I worked my way from there to where I am now while definitely fitting into your category of those the so called "system" couldn't deal with..
If I hadn't learnt to do our thing regardless should I blame someone else?
I think not. Work hard or don't; blaming the system for your failure, while there are people around you who demonstrably made it from worse situations than yours is pathetic in the extreme.
