Try to meditate
Saw one journalist she underwent a yr of experiment to do meditation everyday. Can b v short etc
N noticed gd changes to her mind n I think body too.
So the thing now is how bad is yr situation
What caused it?
Eat better?
But same time watch yr mood because mental can affect physical
The more stress u r mentally , the more u give yr body stress , then give back to mental again
Cycle
I just went to Google pmdd...Hmm u can try tcm too
N exercise
N really meditate then u just see yr symptoms as it is, without attaching any emotions to it. Don’t get frustrated etc. N slowly see how to reduce symptoms
