I'm making good progress with my rehab. I've whittled my friends list down from several hundred to just 26, I look at FB about twice a day and I don't post anything. My timeline has been wiped out of all comments and status. I'm almost there. There are just a few things that are keeping me involved, but I've got rid of all the drivel, viral hoax scare stories and pathetic attention seeking statuses that express a hint of a problem to invite people to ask for more information.
The worst thing about Facebook for me is that it shows up a lot of the stupidity that I'd rather just be unaware of.
