Hi gigipop,
Mums are the most important people in the world, you create life, and nurture it,
Your job is more important than any other, so please try and look at it in that light,
Be proud, and hold your head up high, if your kids make you proud, its you thats done it.
Now that you have some spare time, how about some Charity work?, that self rewarding, whilst helping others.
You've got some excellent advice in the above posts, just up to you to take it,
Apologies Ray, just realised i've said something very close to what you've written.
