While taking I forget the things what i'm talking about when I try to remember I got blanked. I also mispronounced the words even when i'm familiar with them. I have headaches issues from past 1 month in my left brain when i'm stressed and sometimes in right i.e. Only one side of my brain for it I preferred disprin tablet as otc. From last one week I can't sleep properly even i'm not stressed. I also have a history of clinical depression and anxiety. There is something I need to worry about?
