Depressed after looking at Facebook, why do I look?

I haven't posted on FB forever. The last message I made was "I will rip the head off the next person to invite me to play some stupid FB game."

I use fb in a whole different way, partly because I am a 50 yr old mom, the only people on my friends list are people I actually know in person and most of that is family, including my 70 yr old mom and my kids. That is how we keep up with each other these days in addition to ph calls. My son's future mother in law is on it and we talk about wedding plans from 2 different states. So it can be a good thing depending on how it is used. I ignore all the invites and ads. But I agree if it seems just a bunch of people showing off their so called 'perfect' lives, that is depressing. Actually its very irritating too.
