The biggest problem anxiety can cause in daily life is an inability to focus. This can make it difficult to recall words or do other things because the mind is busy with the anxiety issues. There is a saying, "We need to stop to think." That means we needs to stop the other thoughts and distractions so we can focus on thinking about the issue at hand.

It appears you get caught up in the details. These details can cause quite a distraction and limit you ability to focus on the task at hand. This can be similar to ADD/ADHD.

A Neuro Psychologist can do tests to diagnose these issues. It is not uncommon for people with word finding and other cognitive issues to have them due to anxiety and/or depression. Those cognitive issues due to a brain injury usually have a bit of a different presentation.
