I feel for you K.. First, check with your doctor about your symptoms.
Second, work out a schedule with your husband for night wakings. My husband I would alternate every couple of hours. Then one night a week each of us would get an opportunity to sleep in the guest room downstairs for a full night of sleep.
Then, look for a moms support group. I've been in MOPS - Mother's of Preschoolers (you seperate from the kids for some mom bonding with activities and crafts) a couple times a week. Now I'm in MOMS Club. www.momsclub.org I love that we have activities nearly every day of the week to pick an choose what to attend as it fits into our schedule.
I've had a home party based business for almost a year. I love it. It get's me out of the house 4-6 times a month (nights or weekends when my husband is home to watch the kids). It's a party atmosphere so the women are happy to be there. We don't do presentations so I'm just mingling with the guests and helping them pick out jewelry they love and makes them feel good. I've become friends with many of my hostesses and guests. My husband has stepped up to help with our two boys (3 1/2, 1 1/2) and is enjoying that time for the most part - especially when I'm coming home with $250-700 for a few hours work. We just finished out taxes and there are super benefits to having a home based business.
Like the oxygen masks on the plane - you have to take care of yourself so you are strong enough to take care of your family.
Best wishes.
