If you have low self-esteem, Facebook just depresses you further. I only use it for keeping in touch with people via PM and a private group, I very very very rarely take photos and I never put up 'wall' posts or anything like that, on my page there's just loads of tosh about my zodiac sign. I was put off posting regular stuff on my Wall after some idiot in my year who I didn't get on with trolled one of my more open posts, which was after I signed up.

Most of my page are just family, childhood friends and people I knew through my years at school. It's depressing seeing how childhood friends/cousins have changed and stuff and I also feel really inadequate when people post pictures of their social lives, I'm not just talking about the obnoxious ones, even the more innocent ones I guess.

So yeah, it's the best thing to avoid if you have low self-esteem or you're feeling depressed, yet at the same time rather time-consuming/addictive.

Unless I'm missing something, how exactly is it 'obvious' she had mental health issues? I don't understand what is so "sick" about that? It's something a lot of insecure teenagers do (adding mutual friends they don't/barely know etc), and I reckon pretty much everyone has 'stalked' someone on Facebook at some point (whether it's a crush or an ex-partner etc) since it's so easy and you can't see who has viewed your page, just few will ever admit to it.
