thanks for the replies
thankfully my ex is here a lot to help with the little ones right now but it is hard. i think thats what gets to me most, seeing others do things with them that i have always taken for granted.
i have been told one of my main issues is i dont eat enough (due to gallstones) but there has to be a way around it.
thanks for the hint about the sit n be fit, will have a look for that shortly and have a better look around the forum (once ive got a little peace from the younger 2 lol)
