Hi Tracey,
sorry to hear you're feeling like that,I suppose I'm lucky as when I get angry outbursts they never last long,but can be intense &upseting.I was doing meditation for a while which hugely helped with all of these feelings,but unfortunately I stopped practising,
Breathing greatly helps,especially if I'm alone with my little son,I tell him I'm going into the garden for a minute &I kick a ball,or jump on the spot,and finalyy I breathe as slowly as I can,counting up as far as I need to.This is something people often recommend and I never listened but it actually helps.
That's all well &good when you're at home &can kick a ball
BUT the breath is something you have with you all the time,even away from home.It is a powerful tool to help you relax.
I hope this message does not anger you even more!I know when you feel angry &people suggest just breathe,you may not think it is useful advice at all.

I have been using natural progesterone cream since May this year,and I find I am unbelievably more calm now.
I take extra cream when &if I feel angry.

Also I usually notice that the angry outbursts I do have coincide with low blood sugar,which is also more balanced
since starting the cream.
I hope this is helpful in some way.
