Not stupid at all. When my anxiety was bad I was unable to stay in the bath for more than a few moments, I was completely restless.
Anxiety feeds on itself. 'what if'. 4 me anxiety is physical, I don't worry that I will have a panic attack unless my body is in high stress mode, when I feel OK it isn't difficult to go out and about. When at my worse in the 1990s I was unable to leave the house. 'in case'.
Panic attack 4 me begins with sudden nausea, my thighs go weak followed by my calves and I hit the floor. No argument, no cognitive thought pattern, it's physical. Fortunately I have an emergency drug which either knocks me out so that I sleep or it enables me by eliminating the nausea.
I too was calmer by evening, all my commitments were done! It was like a different person and I learnt not to agree to helping with anything because I knew that by morning anxiety would floor me.
As for your husband, he probably can't deal with what he can't understand. Ask him. Otherwise communication will cease which is stressful. "I know that U realise that I'm not myself, I am aware that it bothers you so can we talk about how menopause symptoms are affecting you so that we have a plan?"
I don't know why B12 results would impact on HRT treatment?
