I feel like I've lost my mind sometimes, too. I know that derealization and depersonalization stuff and it's hard to get through because it makes you feel trapped. I have gotten out of it before, though. It takes time. you must be gentle with yourself. Don't expect anything at all. Don't fight, don't struggle. Like noworries said, you need to let it go. Your mind is in crisis mode right now, trying to just stay together. You're feeling separated from yourself and your feelings and world because of the anxiety and worry. It is like the more you fight, the worse it gets. The closer you look at things, the less they make sense.
Take a new perspective. Love yourself as you are, no matter what. be gentle with yourself. Expect nothing for a while and let it all go. Give up like noworries says. That's what I'm trying to do. release the fear that is strangling your life. It's all because of that fear, and fear feeds fear. The more you fight, the more your instinct will be to release more fear and adrenaline. If you feel wonky now, just let it be. You feel out of your mind but you're not really, it's just a distorted perception. Imagine that you're looking at yourself and life through a filter and it's all smudgy. You just need to relax and that filter will eventually lift away.
The first time I went through this I had it on and off for months on end, so it's not an easy or quick road, but it can be done. I'm dealing with it again right now after a relapse of symptoms, and I really think we're going to get through this. It is terrifying and uncomfortable, but we can try to accept it right now. this is us right now, and we're just a little too close to the problem to see it clearly. Let's step back and let it take care of itself and it will work on itself. It will dissipate and the lens will clear.
