You feel like that because you want to be successful like them. It's a normal feeling. I'd be weirded out by someone who doesn't have it. Virtual hug.
We're all just strangers on the internet, but I feel just like you do. It does discourage me. I've cried. I've been angry against people who have tried to help me out of pure altruism. It's hell. People who are lucky enough not to experience this will never understand what's like to have a mental breakdown on a Friday Night at 8pm, in which you question your entire life, while people your age are having the time of their lives partying and drinking.
No matter what you do, keep on trying. That's what I do. There are other things in life who make it worth living besides a salary and a career. Again, virtual hug.
