Short Term Memory Loss

Sigh. My short-term memory loss symptom is getting more and more serious..
In this two-week, the total number of stuffs that I've forgotten is huge.

-First I locked my key inside my room.
-Second I lost my Bros water bottle. I don't have a clue of where I put it.
-Thirdly is I forgot about my handphone on the way I go to friend's house for assignment discussion. But luckily it's safe and sound on my desk.
-Fourth thing is I nearly forgot about my dad's birthday on 25th. Luckily I get to remember it during a boring lecture.
-Another thing is I forgot to bring the city map out last week when I needed it badly. I've circled the place that I was heading. I just simply forgotten about it and left it on the table.
-My Faber-Castell eraser is missing too. I only realise it when I were about to sit for my Thermo test 2.
-I tend to forgot those grocery shopping that was paid by me. In the end, I didnt get any refund from friends. I'm still trying hard to remember where the money has gone to.
-More often than not, I forgot whatever that I wanted to say to people after they finish their speech. It's just all blank on my brain for that instance.

In fact, now I've forgotten what I've forgotten.=.=!!

Just went online searching what is the structure that is responsible for short term memory..and it is called pre-frontal lobe.
"This region is located at the very front of the brain and is highly developed in humans. It is the reason that we have such high, upright foreheads, compared with the receding foreheads of our cousins -- the apes. Hence it is no surprise that the part of the brain that seems most active during one of the most human of activities is located precisely in this pre-frontal region that is well developed only in human beings."The Brain From Top to Bottom

So does that mean that my forehead is not high enough? *Double sweat*

Sigh.
I cannot continue being like this.
If not, by the age of 30, I might even lose myself. OMG!!
I gonna learn to remember stuffs hard. The 1st thing for now is write down whatever that I ought to remember or ought to do when it is still on my mind. I hope I can get rid of this short term memory loss thingy soon.

Please have a hard knock on me whenever u see me leaving things behind.
Please please have a harder knock on me whenever u know that I've forgotten sth twice or more.
Thank you!!
