I am beginning to think that my difficulty to pay attention and extremely bad memory might be ADD or something similar.

I zone out all the time. I don't think I have ever lived in the present. No matter in what kind of situation I am or what job i have to do I cant pay over 60% attention to something. I am very bad at travelling because even though i want to remember the path from a to b i zone out in few seconds then zone in again angrily and then zone out again and the process keeps repeating. I suffer at my studies heavily to due to this. I am always in automation. I cant even remember how that dish tasted like which i was so eager to eat.
I really want to pay attention but even to things I am interested in I cant. We went to a foreign vacation for the first time and even though there were awesome things all round me i still was battling to atleast not be blind.
The things that have always puzzled me were the subjects I zoned out into frequently. More than half of the time they are highly weird, insane, reasonless and stupid.
Like i used to sometimes think what if the person in front me did something strange and how other people would react to it.
Or wondering how this particular word my have been invented.
Or what if suddenly some stupid "rules" came into existance like you cant do this during this and stuff. im sorry im finding it hard to give examples because i mostly forget these things quickly like people forget dreams.

Memories of scenes from movies, some music i heard 10 years ago or something that happened in real life starts being reenacted line by line, action by action in my head as if it is a stage or something. i completely stopped watching TV, movies etc with the hope it will change something. No success. these makes me hate myself especially when it happens during something important and it does everytime. is the rest of my brain that isn't me completely crazy?

My memory and listening skills are another problem. I used to think i was somewhat deaf. Even when i am being yelled at i would zone out for a second and couldnt make out what the word was that someone said. And i even forget to do things that I decide to do after ten seconds. the list is VERY long.

is this ADD and if yes can it be minimised?
