Hormones and mood swings

Last night I was listening to Christmas Carols when I suddenly burst into tears. Today I became very frustrated and retreated to the office so I would refrain from talking to anyone until my hormones leveled out. These mood swings are so new and strange. I do my best to not let them effect anyone but myself. This can be hard at times, but thus far I have been fairly successful. Half the time I go into one I have no idea what started it never mind the reasoning behind it. Lord I pray for understanding from all my loved ones so that I still have friends and family by the time our little blob comes into the world.
