Open Question: Just Feeling A Little Discouraged...?

I remember when I was in High School two years ago (I am now a sophmore in college...) I was like the richest kid in my school. I had 4,000+ dollars and I used to feel like i was on top the world! College came around and I nothing, then christmas came around and I had to spend more and I had nothing again! Finally after a long time I made it back to 2000 bucks, but I am 19! My friends who are in high school have soo much more money than me... like I have a friend who works a lot and he just purchased a 12,000 dollar dodge charger o_0! I also have another friend who is buying another car for 7,000. I am just annoyed because I feel like I am doing bad for myself, the college kid with 2000 dollars. I work 20 hours on weekends and study a lot on weekdays... my friends are in hs and they have a lot more money than me and are able to buy nice cars etc... What can I do? Am I doing that bad for myself?
