Hi hun, stress can have a bad effect, so you really do need to make an effort to set aside some 'me-time'. Do you have a spar nearby? Maybe you could knock the gym on the head once in a while and try the spa ( I know what I would chose!) Or instead of cleaning every day, give it a miss now and then and run a bath with some lovely smellies, candles and a relaxing cd. Put some cucumber slices or cold used tea-bags on your eyes and just wallow and switch off. Then get o/h to give you a nice relaxing massage (should help to get you both in the mood too!).
If Im feeling stressed, I go for a nice slow walk and just take the time to LOOK. Notice the flowers and leaves starting to bud, the birds singing or just the cat sitting on the wall! (Focus on the nice stuff, not the rubbish in the gutter etc! :lol
Get a good yoga book/cd and try out the relaxing poses, or try a yoga class at your gym. Put your fave dvd on to lift your mood (Grease always works for me). Good luck hunny!
