Once you get to that point with yourself then it is also easier to see too!
I must add that this is very sound. I find myself in the same situation. In my own little world, I had a hard time seeing what was real. And I still have that problem, hence all my crazy posts in my threads. But, what Cadet said is so very true. Another thing, posting in others' threads is not only helping me to see things more clearly and detach a little easier, but it also helps me to cope and heal. If that makes sense.
There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
