Jealousy

Soo... deep post from Kira today... looking at friends on Facebook and feeling kind of jealous because they're having a good time without me... Isn't that shallow? Its like, I don't want anyone to have a good time without me, even though I'm clearly busy, and have no way of getting to the aforementioned friends. NOBODY CAN HAVE FUN WITHOUT ME!!! Anyways, wondering if anyone else feels like this, or if I'm just a very possessive, controlling person.
