Blanking out Mentally

I wonder if people go through the same things that I go about dealing with the drudgery of life . I find myself listening to a conversation and not hearing a word . In a flash am out if it or back into it. Do you also feel the urge to be left alone and not be surrounded by any human ??? Off late I find myself preferring to be alone and not seeing a single soul who I wanna interact with . Maybe I just need some time to know myself . Maybe I just need to stop pushing myself to meet the expectations of people ....maybe I just need some help ??
