For the past 5-9months, I have been feeling tired and sleepy almost everyday all the time. I feel as if I have to sleep/rest an hour for every 2 active hours in order for me to maintain energetic, at least. My eye lids would otherwise be freaking heavy.
I have also been loosing concentration and often doing things wrongly at work. Worst, the things that I am doing wrong are so unforgiving that my bosses are so unhappy about me. For instance, there is this serial number of an item in the stores that I have to take down in the log book. It is a simple task. The number is 780546 and 780555. However, I could be stupid enough enter into the log book as 78546 and 78555, with a missing 0 in the numbers. Such similar mistakes have occurred more than 5 times in a month! There were also scenarios where I need to paste barcodes on the items and I pasted the wrong barcode on the wrong item.
I do notice that I often get very nervous when I am being rushed to do things quickly or I am being watched. I would get so nervous that I start to become clumsy, knocking into things around me when I move.
My boss is getting very unforgiving and is getting mean on me for all the mistakes I am making. This makes me feel even more stressful.
Apart from that, I also find myself having poor temporary memory. In one case, I was given a set of instruction through the phone. After I put down the phone, I told myself I will wash my cup before carrying out what I was told on the line. However, right after I was my cup, I would forget about what I wanted to do and I continued my normal job. There are other cases which I couldn't remember things well and often screwed up things at work.
Talking about instructions, I also often have a problem where say through the phone or whatsoever way, when I am verbally delegated with some instructions, I couldn't totally get the whole thing. I would only get the last few words said by my boss. I will need him to repeat a few times for me to slowly process it. But many times after processing the instruction, I will find myself forgetting them quickly. By the time I recall, things would either be too last minute or left undone.
In anyways, I have been screwing up things both at work and personal life. Even my girlfriend has started complaining that I am not talking much to her as I am often tired and sleepy. People seems to be loosing confidence in me.
Is there anything wrong in me which I need to look out for? My parents are worried when I told them about my present condition. Or I am just plainly unlucky these days?
