Ditto Ruth. I tend to visualise and put it in perspective. Eg, Is it really that bad? What's the worse that could happen? It's my choice how I react to other people and situations. Thinking about it in the big scheme of things. Writing all this stuff down helps as well. Having a list of affirmations and your goals or similar on your fridge or in your purse or somewhere you can pull it out and read it whenever you feel stressed and overwhelmed can help you see the bigger picture.

I agree with Lulu too, DH needs to do his bit as well. It goes both ways.
