I get that. All of my friends on Facebook are pretty and talented and Facebook just shows it off. I want to delete my Facebook too because of insecurities but mine started when I got in a fight with an old friend from high school (not that long ago) on Facebook. She said horrible things about me (especially judging me based on the things I wrote on my wall without thinking) and now I just hide. I'm never on Facebook anymore because I usually end up comparing myself to others, like, that person is prettier than me or that person takes better pictures than me. They all just look good on Facebook, but they are not the same in person. At least I hope so. It has really made me question my true friendships in life. But I'm like you. I don't know whether to keep it or not. It's good and it's bad sometimes.
