So basically, I have trouble processing multiple sources of stimulation. I tend to hyperfocus on 1 particular thing and my brain kinda shuts off everything else. For example, if I'm watching a TV show and someone is talking to me, I'm too engrossed on the TV show. I can hear the person talking, but I can't comprehend or understand what they're saying. 

Another example. I tend to struggle with following verbal instructions from people; because I'm looking at them and also listening. I tend to focus too much on the looking part and trying to understand instead of listening and what they said just goes directly over my head?

It's like a hyperfocus on 1 sense at a time. Does anyone have ideas? Is this an anxiety thing? I don't want to say it's ADD because I don't meet enough of the criteria to be diagnosed with ADD
