95% of the symptoms I experience regarding the anxiety disorder (specifically they are more dpdr oriented) are just mental. They can be thoughts or alterations of perception, like if life is moving in "real-time" (probably has to do with stress), feeling fucked up to look or think about my face or my parents' faces, or feeling "stunned".

The thing is that my therapist told me that it's impossible, there must be a correlation between body and mind but it doesnt feel like that. I can be physically and mentally calm but still experience those fucked up sensations. I feel that he doesn't know what he is talking about.

The same goes for depression actually. Someone can be diagnosed with it and not necessarly have fatigue or low energy, maybe they only have the mental aspect of the disorder, like no enjoyment or pleasure in life and feelings of hopelessness.
