Hi! Just wanted to let you know you're totally not alone in this. I've also sometimes felt like I'm in a VR game of some sort which is sooo weird and scary but I truly believe it's just a dpdr symptom.
Personally I've noticed that most of my symptoms are the same, they're just explained differently from time to time. So while i sometimes feel like I'm in a VR game, that's the exact same thing as having reality look a little deformed, or looking at your hands and not feeling connected to the body. And for me, the actual idea of everything looking like a simulation or VR is what terrifies me, because I start to wonder what would happen if it was true. But the actual sensation isn't as horrible as I make it to be. The thoughts is what makes it worse.
I don't have any specific tips other than to stop obsessing over the feeling that everything looks deformed. I know that's literally impossible in the moment but try maybe writing down exactly what you're feeling and then deciding to leave it at that. It's truly the thoughts that are increasing the feeling. It's like an endless circle; uncomfortable and scary symptoms lead to catastrophic thoughts, which leads to anxiety, which leads to more symptoms and then even more catastrophic thoughts. This is why it's best to try to decrease our catastrophic thoughts.
If you don't find it comforting to write down what you feel, I've got a technique that's helped me quite a bit. (I learnt this in CBT therapy so it might not be for everyone but consider trying it out!)
•Try and think about your symptom/catastrophic thought (for example you going insane).
•How much do you believe in this thought from 1-100?
•What's your proof that this might be true? (In this case what's the proof that you'll go insane?)
•Which arguments speak against your fear of going insane?
•How would someone else look at this situation? Is there any logical explanation?
•How strongly do you believe in these thoughts now?
If this won't help you. Know that you're not going insane. This disorder/anxiety symptom or whatever it is will not make you insane, and you're not insane for having it either. I've had a lot of scares where I have literally felt like I've lost it completely, you'll see some of my posts on here lol. These symptoms might make you feel like the only possibility is that you have gone crazy, but you haven't trust me. The human mind is super weird, it'll make our bodies and thoughts change a lot even when we don't want it to. But it's completely natural. This is a defence mechanism, nothing more. Also what's comforted me a lot is knowing that if I was going insane, I wouldn't have noticed it. And I can tell you're really anxious about all this, which only proves that you're not crazy.
These techniques and mindsets I'm talking about, they're not easy. But as time goes by you might find yourself feeling a bit better. Some days are worse, some days are better, and some days you might just want to give up. But please don't. I know the feeling trust me. This weird "disorder" is pure torture, but hold on for just a little bit longer. It'll get better eventually even if recovery seems far away. Lots of people need you here, so keep going! You matter and you're so much stronger than these symptoms.
Also, we're almost exactly the same age and really want you to know that it's really not the end for you. Yeah this sucks but when you're out of it you'll appreciate life so much more. We've got a lot more to experience so don't give up!
