if you let go of the resentment for a moment there's a lot of value in not getting everything you want from your parents. I can relate – I too have a sibling who was given a house lol, whereas the most I ever got was they paid about 20% of my tuition fee for university (which is about 1/300th of the value of that house). And in contrast to me this sibling's physical health is in perfect condition. But honestly I don't want to get anything for free, because I know what that entails down the road; laziness, entitlement, and absence of purpose. I feel sorry for this sibling because those traits are manifesting themselves in a huge way – and will keep doing so forever.
