These attitudes of what is good or bad or is something to be embarrassed about are also intimately projected (often subconsciously) by our friends and family. Most people can list off one thing inside their heads that no one else on the planet knows about them. Some people may have more. I do, for one.
In a perfect world everyone would have at least one place where he or she could feel entirely safe. In reality, so long as there are other people involved in that space, someone will always pass judgement. Asking people to not express that judgement is the usual focus of someone trying to make a safe space. So is the only safe space inside one's own mind, because after all, what others see are projections of us, as there are aspects that are always publicly censored?
I try to make my blog a safe space by not accepting derogatory views of mental illness, but at the same time, I cannot be totally honest due to fear that someone may identify me, and, well... stigmatize me. Even with close friends, I withhold mention of thoughts I have or stuff that's happened simply because I know they'll never get it. When I am alone trying to fall asleep, I fear that all these different projections of me, the placeholders, have become so knotted and twisted together with my true self that even I don't know the difference.
And if I don't even know who I am, then what do I know about everything else?
