Dilemma of the 20 year old kid.?

I've grown up my whole life, spoiled, by my mother. No i do not come from a rich family, or even middle class in fact we are quite poor. What do i mean by spoiled then? Up until high school my mother planned my whole life for me, i had 0 worries in the world, everything was fine until.... my mother left for motherland for about 1 whole year. I was a sophomore at that time, i was left by myself without knowing what to do. I'm going to stop my little story there, Am i even right to have that thought? blame my wrong doings on my parents not teaching me better? Should i not be learning and doing by myself? i grew up disregarding ignoring all that is bad. And now my sense of whats "right" and whats "wrong" is completely haywire. I have been running into trouble getting locked up for misdemeanors, and i want to change. Where do i start? i am already one year behind in college, and still messing up.
