Should i feel bad for being rich?

I constantly feel bad for being rich. All my peers are considered "unwealthy" and live in small flats. I live in a house that is quite big with marble floor and a lift. I have just moved to this house and it is for rent so we can't make changes. Whenever friends come over they gasp and talk as if they have just entered a palace (whoa) I constantly think " why should i live in a massive house whilst there are people who are starving"Along with the house everyone in my family has iphones (my dad and brother have the 6 and my mum has the 4) and as soon as someone asks for something they get it. Also when i go out with friends my parents give me double the amount i should have even when i ask for less ( i really appreciate this but i feel bad because i feel i don't deserve it and that there are people who really need the money.) Back to my house, it doesn't feel homely at all and as soon as i enter i keep feeling like i'm a typical spoilt brat entering a rich family. House and that my family are like strangers. I used to live in a nice cosy flat and i loved it and felt at home and close to my family but now i've moved to this house that seems like a typical snobby rich families house. I appreciate everything and i have manners and i don't act like a spoilt brat but people always think of me as "the rich kid" and i always feel bad. Most of the day i just say to myself "you are a spoilt brat" Please let me know your opinion. What should i do? How should i feel?

You're not a 'spoiled brat.' If you were, you wouldn't feel guilty about your wealth!
It's natural to feel guilty to an extent, especially when you are surrounded by people less privileged. But it isn't your fault, remember.
It sounds as though you prefer homely comforts to riches, and the cosy environment of your old flat rather than the strange show-home feel of your new house. Is there any way you could move back to your old flat (or a different one) if you're not comfortable?
It's great to have money, but as you've realized it doesn't always make you happy. The move has distanced you from your family. Expensive gifts and handouts won't make up for emotional detachment. Take the time out to do things with your family. Spend money on experiences, as opposed to things.
And if you still feel guilty and over-privileged, why not consider volunteering for a charity? You can't help being born into family wealth, and you shouldnt give yourself a hard time over it. But that doesn't mean you can't contribute in some way and help out those less fortunate in your community. Maybe think about volunteering at a hospital or a homeless shelter?

YOU are Not rich. Your parents are
