It is worse for some women than others. I would get some of the similar feelings during my time but wouldn't be so vocal about them. I do cry a lot and freak out over little things, or I can depressed and think that everything in my life sucks. I have been taking an all natural pill for the last 4 months called Dong Quai. It supports the female reproductive system. It also has Tang Quei Root and Chamomile which help normalize the challenges associated with a woman's cycle. It has worked for me in a large way. In fact about 2 months ago my husband said to me...I can not beleive how long you have been in a good mood. LOL---it means a lot to him...and me. This pill is all natural so there is no chances of being dependant on it. That is a big deal to me. If I have missed taking it for a few days I do not get the symptoms back 3 times as bad or anything.
Maybe see if she will take it just to try. Not only will it be better for you but also for her. She will feel so good.
