All anxiety type personality issues are somewhat similar which can lead to confusion of differences.
I guess the main difference is the individual in his or her propositional attitudes.

There would be other influences to this such as at what age these anxieties first made impact to the individual because early learned coping methods would be different to someone who has later onset anxiety. Other mental/physical issues would also add into the equation of personality shaping.

What I am trying to say poorly is anxiety can look the same but it's the shaping of the person due to their experiences and mental attitude which makes their personality.
