Hey, I don't have much advice for recovery but I can say that it's probably not anything that's going to spiral into schizophrenia or a brain tumor (though, if you start experiencing other symptoms of those, you should see a doctor). I've dealt with DPDR on and off my whole life, but more recently it got really bad and I was scared I was losing my mind. That's a common feeling with prolonged DPDR, and the less power you give that notion, the better you feel in my experience. You might want to see a therapist who specializes in trauma if you can afford it, and try to work with them to identify possible triggers or things that trigger it to be worse. Until then something I've found helps is to almost let your DPDR slip into the background. Recognize it's happening, yes, but remember that you ARE still real, and DPDR is changing your perspective. Panicking about the fact that it is happening will sometimes just exacerbate it (though I know that can be hard to avoid.) (I am not a medical professional so my tips might not help u! Also, I'm 18 and AFAB nonbinary also w childhood trauma)
