Am I retarded?

Here's my whole dilemma; I'm 24 years old, I live with my parents, I've been unemployed for four months and I'm literally flat broke. I'm also an art school senior who's flunked cles because of procrastination, laziness, and just feeling unsure and delusional about who I am . My employment history is full of gaps and weird patterns (fired from three menial jobs, also). I have few friends and find it hard to interact with people, as I tend to zone out or blurt out weirdly dumb things. I feel like I've drifted my way through life with my eyes half shut and they've just recently popped open, and I'm TERRIFIED! I don't want to be some poor, lonely eccentric. I'm a 6'6", acne ridden, sinister looking and possibly an idiot. Any thoughts on what a recently self-discovered moron can do for himself? Or what a challenged person (undiagnosed?) with talents but little in the way of competency can do to integrate himself and start experiencing life age appropriately? Be honest.
