Returning to work soon..

Hi Mummies.. I am returning to work in a weeks time after 6 months extended maternity leave.. Have been feeling very low and upset.. I have been taking care of my lo on my own and a helper has just arrived to take care of her while I will be at work.. She is doing a good job so far but you know still that little anxiety and fear sets in each time I think of my absence.. Looks like I will have more seperation anxiety than my baby ;( How did you all overcome this feeling?
