Should I seek medical advise?

So these past months I’ve had non-stop nausea, extreme dizziness. There’s was a specific day I just got home from work and I began to clean and got dizzy real quick so I lied down and it lasted as long as 6+ hours . I also have extreme cause of forgetting within a minute. I have trouble remembering the easiest things ever. Such as my bosses code for the register. He repeated it to me over 20 times in front of me but even then I couldn’t get it right and panicked almost crying. I forget quickly on everything I say within a minute. Should I see my DR & see why I can’t remember ? It’s starting to bring me down a lot. I cry over the fact that I can’t remember what I just said when I’m being asked something. Can any one relate ? Or any advice please ?
