I feel like I don't deserve a lot of the things I don't have?

I have a lot of things (tangible and intangible) in my life that I feel I don't deserve. My parents buy me these things, though, because they think I deserve them. They say that I'm a good daughter because I am smart and study hard and am at a reputable state U, I don't drink, smoke, or make other bad life decisions, and I don't ask for a lot in the first place. They recently bought me a car, and although I am very thankful for what they bought me and I like it a lot, I feel like I don't deserve something that expensive. I feel like I'm not doing enough. I don't have a job, although I plan to have an internship next spring, but I feel like I still don't contribute enough. Many of my friends seem to do so much more than I do and they have less and I feel so damn spoiled. Same goes with the other things I have, my computer, phone, some clothes... Does/Has anyone feel/felt this way?
