I started experiencing this when I was 10 years old when 1 day I got so overwhelmed with thoughts that I could not breath I started crying to my parents that I was choking they rushed me to the hospital and they ran a bunch of tests nothing came out it kept happening for another few weeks until the doctors figured out I was just anxious. I continue to experience it the choking later got accompanied by feeling dizzy like everything around is revolving this later leads to feeling unreal now this is the worst because for so long I could not even explain what I was feeling I just remember feeling as if everything is unreal and is a dream even as a child I would try to put myself to sleep in hopes that when I wake up it won’t feel like a dream I am not sure if I ever stopped feeling like that or just got used to that feeling. I am 20 now I moved countries goer school and now i am having one of the biggest depressive episode this is the first time I am telling this to anyone.
