Anxitey

What is it with this weird, spontaneous anxiety? I never had it with the girls, so it is really strange. TO go with it, the emotional breakdowns? Come one! It has happened twice in the last month, and I don't know why. Is it the hormones? Is it knowing precious this baby already is? Is it the fear of handling a family of 5, plus a full-time business owner in a sucky economy? I don't know what it is but it needs to go away, pronto! Anyone have this?
