is this dementia?

im in serious deep shit. my memory starts to fail and it seems like i have signs of disorder, which have sonehow affected my ability to carry out everyday's task.....

one moment, i may be talking to my mom  sharing our thoughts, and we stepped out of the train, i immediately forgotten what i have talked about.

this morning, i was in the toilet, washing up and preparing for work. without any thoughts, i just picked up the toothbrush n started brushing. suddenly, i take a good look at the toothbrush and stared blank. "eh??? this is my toothbrush meh? is this mine? which is my toothbrush?" i have been using them for months, but yet i can suddenly forget which is mine.

and before i left for work, i remember putting in my laptop and staff pass into the bag. guess what? in the end, the staff pass is not even in the bag at all!!!!

conclusion.... is either something is playing a treat on me, or my memory really start to crumble liao.
