> Does anyone else feel extremely guilty about this?

Not really. I feel like I've put in the time and effort (along with a little luck) to get to where I am in life.

Unfortunately, life is unfair. While it was nice having parents who supported me, I feel like it's just an advantage in life I was fortunate to have. On the contrary, I'm a short, unattractive, non-white male living in a city that's 90% white; there isn't much I can do in that regards. That's just life.
