Differentiating between psychological and physiological


Just wondered if anyone else has difficulty working out which are physiological feelings and which are psychological feelings? For example I might have a headache but don't realise it and just think I am in an angry mood. Only when someone who knows me well points it out that I might have a headache and I take some ibuprofen and it goes away (and the anger subsides) do I realise it was a headache. Also vice versa when I am anxious I sometimes interpret this as having a cold or some sort of virus as it makes me feel lethargic and I ache. Only when I realise the trigger for it and the anxiety passes do I realise it was anxiety....

This inability in its self stressed me out as I never really know what is wrong until afterwards.
