People make people be that way, not life.
The thing is, in my experience, the more you let people into your true emotional and mental state, the more they judge and resent you for spoiling their news feed. The more they block updates from you. The more they groan when they see you're online again.
It's easier for people to get fed up with you when they haven't walked a mile in your shoes, or alongside you.
People judge and criticize what they don't understand.
Which I suppose is a step up from burning and murdering people that were misunderstood.
And that's the thing about online personas. You can be anything or anyone you want, so you can pretend to be happy, but after a while even that gets too much. I don't actually post on my fb much anymore because 99% of it would be negative or complaints. It's much easier for me to cope by leaving them the impression I'm just too busy to post progress, than to say how I feel and get bombarded by questions and/or advice. I'd rather get on with it and deal than to have evidence to scroll back through. You try forget the bad times, so why memorise it in cyber space?
Albeit, forums are different to youtube to fb and such.
