As suggested above get a bit of exercise, come home have a nice bath with smellies and do something that you need to focus on, puzzles, embroidery, anything really
Then tomorrow take a piece of paper write down all the things that are making you feel fed up and cross out all the things you can do nothing about That alone helps as the list usually goes down by a big chunk
With the others think of one thing you can do to make each one better... then choose three to do That way you will start to chip away at the 'sugar' stuff and start to feel in control again If possible find one thing your husband can do on a couple he will feel he is helping
