Sounds like me when I am under a lot of stress. I call it “Nintendo World” because I am so disconnected I feel like I am playing an avatar of myself in my daily life. I HATE that feeling!
I agree with what was said already. Self-care, up your meds, diet, and exercise. I would also add sleep and maybe some anxiety meds to supplement adhd meds. I am currently on 150 mg sertraline (Zoloft) and 15 adderall xr. I have not visited “Nintendo World” since I have been on both meds (about 1/2 a year). Hope you can find some relief soon!
