I know how that feels. Whenever I'm with any of my family usually they will all be talking to each other but after several minutes I find myself just sitting there staring at a wall because I don't feel like I'm a part of my family. I definitely feel the same way about mine.

And yes, it is about you. You are yourself, so of course you want yourself to feel good, and that's ok. You can call it selfish or whatever you want but there is nothing wrong with it, it is our nature as humans.

Man, come to think of it I couldn't feel any more alienated with my family. I don't like my family at all. My whole family has severe communication issues. I swear I'm not like them, I'm the different one, but I've still sufferred for their ridiculous crap that comes with being born into such a family.
