My derealization

My name is Vladislav. I am 16 years old. I would like to consult with you. About 3 months ago, I started derealization (everything seems unreal) - I can’t normally concentrate on something, the light has become somehow sharp or something (I feel uncomfortable when going out). I look out the window, everything seems unreal. It seems that there were no psychological injuries, only recently we moved to another apartment.

I read on websites that such a feeling can come after stress, frustration, but recently I had some kind of fatigue in my legs, too lazy to go outside, my legs became wadded. During the day, sometimes I want to sleep, it seems that my brain gets tired quickly. Recently, my neck began to hurt or get tired, so to speak.

I read that derealization may also be due to the fact that the venous blood flow in the neck is disturbed. So I think because of what derealization began, I remember everything that could be its cause, but I don’t even know how it started. It was great in the summer, there was a lot of energy, but now I just want to sit at home and watch test-antibiotic.com TV or sit at the computer. In the evening I almostI go to the skating rink every day , but it doesn't help much.

This illness of mine really interferes with my life: there are no such emotions that I used to have, I looked at the world differently, and now somehow the day goes by the same way, I’m too lazy to do everything. But my different emotions have not disappeared, I still joke, I laugh, I communicate well with friends, but this fatigue in my legs and lethargy with derealization worries me a lot. Maybe someone had something similar?
