M.G.
First of all, I agree w/ the other 2 ladies. Second, I will give you some HORRIBLE ADVICE. Bitch and complain as much as you can to at least one person. That person should probably be someone like a sister or best friend. Not your husband or mother. Let out as much as you can. This is what I do. It makes the stress and tension I feel much easier to deal with when I am around them. Now by them I don't mean my in-laws, but that's besides the point. My advice will help only in the area of not exploding the next time this situation arises.
As I said, HORRIBLE ADVICE. I just had to get that off my chest. Good Luck and God Bless. You'll need it.
