Hello everyone, I'm 21 years old . I have been experiencing some symptoms lately and I'm not sure if that's anxiety disorder or what. For the past couple of days I feel a weird feeling of sadness and loneliness , like the world has become darker. And I also feel that I'm not here, meaning i zone out alot and feel like my environment (home for example)is a bit strange. That feeling usually comes during the night. I also sometimes experience panic attacks or feel suddenly extremely afraid/uncomfortable. Is that related to anxiety?
