I learned this through my wife and her experiences: The best way to take hormones is the bio-dentical type. A "test kit" is availiable where you use a cotton swab to collect saliva and send it to a lab. They test it to see EXACTLY what your hormone levels are and what you are lacking and in turn your doctor can prescribe the exact amount you need an eliminate the guess work. It has worked very well for her, much better than the "trial and error" method.
Hormonal imbalance can always influence your general moods and your emotional sensitivity. Just like a pregnancy or the period. As estrogen pills are hormones, yes I guess it would be normal.
If the influence is so intense that it bothers you, you should talk to your doc. Maybe there is an alternative product with less side effects.
no you might had overdose of it.
yeah it is normal
