Cannot memorize. Things in another?

Hi, Hope this letter finds you in good health..!! I wanted to inform you that, quite often I quickly tend to forget thing's.. sometimes within an second; like for one moment I knew I had to check a report in my office while on other moment I completely forget that I've to do that. Also, many a times I go to my kitchen for grabbing may meals or like just to have a water knowing.. but as soon as I enter in kitchen I think like "Why I'm here??", I know I had to do something but couldn't just memorize enough that I was there for my food or water etc. It's just this issue I'm facing lately and I'm afraid this might affect on my work life as well as personal too. However, when it comes to remembering the old memories or some vital information on past days which needs to be recollected I'm very much good in it and indeed remember it faster. Is this some kind of short-term memory loss that I forgot thing's in one moment and remember things in another?
