Sometimes EF depresses me even more because I'm so ill and/or I'm under the influence of my painkillers that I can't just spit out constant reviews like everyone else. It's hard to focus and write an extremely useful review when you feel terrible or your brain is slow from painkillers.
Also many of the forum posts are about being married, having SO's etc. It's extremely depressing for someone like me to get reminded of how alone I am, but I still come here every evening.
EF usually does more good than harm for me though, so I guess that's why I stick around. Not to mention, it allows me to have some sort of contact with the outside world.
