Is FB worth it?

Lately, I get to be inactive in Facebook, a.k.a, FB.  I am quite disappointed or I should say dismayed to read some sad news.  On the other hand, I am happy when I read good news.  In FB I witnessed several relationships getting better and relationships getting bitter.  Anyway, the reason why I wrote in my blog was the result it brought to me when I use FB. Guess what? I tend to compare myself from the statuses, updates, exciting news that I read from the newsfeeds.  And that made me feel sad a bit that I prefer not to post any updates and news about me.  Is it my insecurity? Is it my low self-esteem or what could it be?

So yeah, I don't know if posting in FB is really worth it or not.  But as far as I am concerned, FB is not my priority anymore. :(
