Let me formulate something about family values and summarize a couple of points here. This could be especially useful to anyone having pressure issues at home.
1. You didn't choose to have any of your relatives, hence you are free of any responsibility regarding their lives. You are only responsible for your own life and your own problems. If your parents or siblings require help and respect from you and you don't feel like they deserve it, don't feel guilty. It's their fault that you are left with such impression. You have no obligations to your family what so ever.
2. Your parents chose to have you, hence they are responsible for your well-being. Here's an analogy that might help - choosing to have a pet and taking care of it doesn't require any care on the part of the animal. Hence, whenever you need help, your parents are obliged to please you, no matter how old you are.
3. Your parents' property is also your property. Your own property is exclusively yours. Family members cannot take credit for providing you with food and shelter. That's already yours - you earned it by being their child. Parents, on the other hand, can't pressure you to share your property with them. If you don't feel like doing that, it means they haven't earned your respect and it's their fault.
4. Having a sibling is a relationship equal to having a roommate. You are to share only what's given to you by the family. Outside of this boundary, each person has their own property and is not required to share it with their siblings. Help and respect should also be individually earned. Nobody chose to have a sibling, unless of course, you like incest. Hence, no responsibility should be taken upon each other.
Note: I have changed some of my views on that subject. More on that here: Finally Free
