I hope you are well and I hope that you can find a doctor/psychologist that understands you soon. Sometimes I think anxiety can be a bit of a cop-out answer a lot of professionals can give honestly. You know what you experience in the world. Please don't give up on finding someone.
In the meantime, have you done a grounding box before? There are many really good videos on youtube on how to make one. It's a box where you put a lot of different things that ground you in reality more. So for instance, the smell of citrus can really bring you back to the present (I use lemon and ginger tea bags) making one can be really fun and calming too, it helps me a lot
Another thing that might help is getting enough sleep at night. It sounds super obvious, sorry, but just waking up earlier in the day and such (if you are not doing already), getting enough hours in, that can make a big difference in just how clear your mind feels.
And last... if there is something in your life that is causing extreme stress or panic or depression - tackling that core problem really can make a big difference. I'm just speaking from my own background though (my symptoms are more intermittent and crop up if I get too overwhelmed). So if there's something that you're escaping that's been there for 10 years, I hope you can find a way to get yourself out of that situation, or move forward, whatever you need. Even if it feels normal the tiniest change in the right place can help- like not using music in earphones to block out the world, that kind of thing.
I wish you all the best, and I'm sorry you feel like this because it's kinda another plane of hell honestly- still even though the world feels fake the happiness and love in it isn't. That's the first thing that became real for me and I hope it can become real for you too soon, or even just understood. Take care.
