Flowingly: If you're still awake at this late hour, know this:
1. You are not, at all, alone in this. You feel like you are. That's the nature of the illness. You feel like you're the only person existing in your own crumbling world and that all the reality you thought you knew is shriveling up in front of you like a dull illusion. But you aren't the only one there. There are multitudes of people going through EXACTLY what you're going through right this second. RIGHT THIS SECOND. I mean, i've been there before...others on here have been there before...but others are going through this simultaneously with you. You should know that.
2. I have been there as well. Up late...assured of insanity. And i mean ASSURED. Positive that you're going insane...that your brain is prepared for a meltdown...that reality has all been a big horrific memory and that you're headed for some sort of uncharted oblivion where you'll have not so much as a Virgil to guide you. It's a lie. You'll be fine. It sounds ridiculous, but you will.
3. DP is a product of anxiety. You're perpetuating it by worrying about it, but even you with all the energy you're devoting to it...even you cannot harm yourself. Your mind will survive stronger than ever. And do you know how I know this? Because anxiety can only make you BELIEVE that you're going to die/go insane...it can never actually do it. This is common knowledge.
What's happening to you right now...as absurd as it sounds since it appears to you like the world is falling down around you...is nothing but a regular good ol' fashioned DP/anxiety attack...and without any reservations, i can say to you that...while you might not be 100% tomorrow...in fact, i know you won't be 100% tomorrow...but you will be a little better over time...and then as more time passes you'll get even better. You'll have dips and dives and ups and downs, but you'll adapt...and then, before you know it, you'll get better, and you'll wonder what all the fuss was about.
Good luck Flowingly...and don't worry, you'll get better.
