I stopped using Facebook a few months ago because I couldn't handle how it made me feel. I am bootstrapping a start-up ,working insane hours and depriving my family of the comforts/luxuries that I could have afforded when I had a corporate job. I am really happy that my friends are spending their summer vacation at resorts/beaches etc.; I feel horrible that my kids as stuck at home and they can't have the kind of stuff my friends' buy their kids and it is all my fault. I am not jealous -- I feel guilty and facebook updates from my dearest friends exacerbates my guilt.
So I stopped using Facebook temporarily -- I will be back on it when I can buy stuff. m
