to the op.
never quit on a bad day, never quit at night when things look dark (literally)
realize that nursing tends to get easier each week, so set an attainable goal for yourself to continue for another week or another 3-5 dadays and then re-evaluate.
know that even if you wean you will never be the same. You are now MOM. You will be needed, sometimes only Mom will do, even for tiny babies who are fed by bottles. Baby developementally their brain still doesn't realize they are separate being from mom, and they kind of freak out if they aren't with mom.
taking hormonal birth control doesn't make your hormones normal, they just make your hormones different. hormones while breastfeeding begin to settle down somewher between 6 weeks and 12 weeks, and you are gettig pretty close to there.
Feeling touched out is not exclusive to breastfeeding moms. it is ok to hand baby to dad and make dad be in charge. if you want to pump and give dad a bottle do so, if you think you are going to go crazy, give dad a bottle and a can of formula and go do something without baby. For a lot of moms, a BREAK is the answer, rather than weaning. For other moms, giving themselves permission to give a bottle of formula once a week or once a day is the answer to staying with it so they can continue to nurse.
Regardless of your decision, be sure that you change slowly from nursing to formula, so that first bottle of formula that releaves your stress a bit is the beginning of weaning. but it doesn't have to be all or nothing. I know moms that fed bottles during the day and nursed nights, mornings and over night for 8-10 months. what works, is what works, eh?
