Since several days i have been feeling extremely anxious with a weird suffocation feeling despite my oxygen levels being normal, it mostly happens at night like a weird void or an overwhelmed state of confusion it sometimes even happen during the day and usually when im alone in my room , and the moment i enter a little crowded place with a lot of noise or horns i feel numb and confused like brain is freezed along with a weird sound or sensation in my ears , several times even it happens like someone is calling or saying me something i am listening to them but i get numb and confused what they said randomly zoned out . I am not even able to sleep at night since several days the moment i get on my bed i feel extremely anxious overwhelmed and suffocated i feel thirsty every few mins and my mouth dries after i get on my bed it affects my sleep cycle sometimes i dont feel sleepy till 3-4 am , due to this i usually get a gap of 14-17 hours between my dinner and brunch
