Having ovaries removed can really throw hormones into a frenzy! If you suffer from PMS try to imagine having it all the time 24/7!
It can manifest in several ways and unfortunately your Mom seems to be getting the worst of it.
Most of the time she probably doesn't even realize that she is acting in such a crazy way. That's the way it works. At the time when she is at her worst she feels justified in her irritability and anger. There are probably also times when she looks back on her day and thinks "Jeez, I can't believe I said that, or acted that way, it seemed so normal at the time!"
All you can do is try to be patient with her and maybe even avoid confrontations with her when she is acting "crazy". Try to remember that she still loves you, but she really can't control the way she's acting right now.
At a time when she seems calm maybe you could talk with her and delicately point out that maybe she should see her doc about her "spells" of irritability. Her doctor may be able to help her out and give her something to help "balance" her hormones.
I know it sounds amazing that removing one tiny ovary can cause such turmoil. Ovaries are a very important part of a women's hormonal balance.
Remember that your Mom is suffering too and very likely is remorseful for her anger and "tirades" after the fact.
Once again, try to be patient, and maybe after her hormones settle down things will be better...Tagger
