I possibly can't offer any more advice than the others already have, but I just wanted to stop by and say 'hi' and let you know that I am sure you will find wonderful and genuine support here on BB. I've been a member for over a year but have just started reaching out on the forums, and that in itself feels like a step in the right direction for me.
I too struggle incredibly with bursts of anger. My children are tweens/teens now and are well and truly over my moodiness. My psychologist today suggested I get back into meditation. Would this be something for you?
To take a few minutes each day (perhaps first thing in the morning/as you go to sleep at night) and listen to a guided meditation could make a positive difference. I was recommended to try Palouse Mindfulness, but there's plenty out there if you can find someone you resonate with and are comfortable listening to their voice!
Louise Hay is all about positive affirmations - which can sometimes seem so far from your reality in the moment, that it just irritates the heck out of you - but I know from experience it does eventually help!!
Sending much kindness and support to you and your family,
