Health anxiety kicking in again and I thought why not turn to people on here to maybe calm me down and reassure me I'm not dying. So today I have cleaned my room then showered and everything was fine and then I had some coffee and now I feel really faint. I had to lie down with my legs up as it felt my blood pressure was low and I know that coffee can cause anxiety but usually it gives me fast heart rate and buzzing feeling in my body but also I was thinking maybe I'm feeling like that because I do suffer with iron deficiency and today I cleaned and coffee also isn't very good for iron as it kills it so maybe that's why I'm Feeling faint but for some reason I keep thinking oh god what if it's my heart and I'm dying. What if I pass out. And all that and makes me want to cry too which is why I'm trying to believe it's just anxiety kicking in thanks to caffeine but somehow I just can't get it to my head and I really don't want to start panicking coz I'll probably feel worse so I'm just wondering is it normal I feeling faint after coffee or maybe cleaning and that i shouldn't worry about my heart?
