Is it ok to feel the wanted of having a different family?

Of course that's okay. Sometimes we have disagreements with our family members. Sometimes we have such different worldviews that it can feel like we're from different planets. After all, we don't choose our family! We were born into it. In the perfect world, families would be a safe haven for us to return to when we need help the most. But in real life, sometimes certain families don't serve that role. I wouldn't feel guilty about your feelings, but I would try to relate and communicate with your family to the best of your ability. If that still doesn't work, try to build a support network of friends that can serve as your second family.

Of course it is. Even though, by general definition, a family is blood related, anyone can be considered as your family. Unfortunately, there is a nearly limitless number of cases where your blood family acts in a different way than what would you consider to be something that family does. There is a lot of spousal, sibling and family abuse out there, and wishing a different family for experiencing familiar love and bond is normal. There is no shame in it. You define and dictate your family, and nobody else can tell you that blood family is the only true one.
