hormones

Can hormones have anything to do with anxiety or heart palpitations?  I am 35 and had a hysterectomy about a year and a half ago.
The thing is that when I take the primarin I get REALLY irritable and jsut plain nasty. However, I have read that hormone imbalance can play a role in anxiety. So i don't really know what to do.(Take the pill and have my husband walk on eggshells all the time or don't) The pill is 0.625 but i bite in half-it still makes me mean. (and the heart palps (PACs) seem more frequent after i take it to.)
I am on 20 mg of Buspar, which i have been on for a month, and feel no difference in the anxiety level-in fact i feel somewhat depressed, (never felt sad before)
ANY advice would be appreciated.
(am also in therapy)

Hormones can play a role in the development in the symptoms of anxiety. You need to talk to your gynecologist on weighing the risks and benefits of being on an hormonal replacement therapy given the effects of the medications.

Usually, a discontuance of taking the premarin, anxiety and depression improves without taking other medications. You may also consider consulting with a psychiatrist to rule out if your symptoms are from the medications or not and if you will benefit from changing your Buspar or not.
