Considering most people here have DP/DR continuously, it's common for some to get flashes of reality and not the other way around. I don't think I've experienced this yet, but as far as I know it's not uncommon. But scared and shaking? People are generally happy, because the reality mans the DP is gone, at least for that moment.
That's a really moving story. I came close to tears there. How can people be so cruel...I'll never know. Really glad to hear the DP at least went away for a bit. I have yet to experience that, but I haven't had it for very long. Your story gives me hope.
Welcome to the site! It's a good place to vent your problems, and find some answers from all the other like-minded people. I know when I first registered here I spilled my life story in my first post. Made me feel better about my situation. That's not for everyone mind you, but you usually get good support here.
