yellowjo - It's known that when women live to together their cycle will often shift so they are in sync. I expect you are simply picking up on your daughters cycle and probably responding to her hormonal moods.
Also, you could simply need some Omega 3, Vitamin D and magnesium - in mid winter we often get low on Vit D due to the lack of sunshine - Vit D is great for lifting mood.
A few small lifestyle changes can also work wonders - have a look at your diet and check it is well balanced - are you getting out for brisk walks or practising some relaxation techniques to help control your moods?
Don't forget to have some ‘me' time - when there are teenagers in the house this can be stressful and draining.
Don't worry about Christmas - it's a stressful time and often brings out the worst in us all.
Menopause can mess with your head - so don't be hard on yourself - you probably need to put yourself first a bit more. DG x
