I'm sure all mothers know how you are feeling - I certainly do. when my four were little I spent all my time walking the corridors, like you I wondered what on earth i was bothering for. I can only echo the advice of the others - keep praying and reading your scriptures (satan wants you to fail) and ask for help. I'm the relief society president in our ward and I was asked to get help for a struggling mum. the young women were really keen to help and so were the older women and the woman was able to catch her breath and feel a lot happier. your baby will grow up so quickly that it'll take your breath away. this is one of those darn tests that we're given so hold on tight and ask for help. as for your husband, keep praying and keep trying to be a good example. we all fall down sometimes the important thing is to keep getting up!
