Can't indulge in any activities. It is?

I am having problems reading a book, watching a movie, playing any game, talking to someone else, slurred speech, while doing those activities. I can do those activities but while watching a movie or reading a book or talking to someone else I cannot indulge into that completely and due to that I cannot enjoy any of those things. Example 1:- Suppose that if I play any movie so at that time it feels like the information of that movie is not going into my mind and due to that I cannot make an interest in that. Example 2:- While reading a book the same thing happened with I can read the sentences and also I can understand the concept of that but I cannot make a whole picture of it in my mind and that is why I cannot enjoy that as well. Example 3:- While talking to somebody I cannot focus at all and that is why I cannot enjoy that as well. Any idea what it is? I have been suffering from it for more than 1 year
