Your intact family sticking together for your childhood and making a sustained sacrifice for your benefit already represents several awesome advantages many, many, many kids will never enjoy.
You didn't eat out much so... home cooked meals most nights?
You lived in a good school district?
You had parents and/or other family as a support structure for 12 years?
You had a dad?
What is with this sentiment that we have to try to make people ashamed for doing things the right way and working hard?
Be proud of what you have accomplished. Fuck the people that want to tear you down because there's some poor wretch that "deserves" a shot more than you do.
