Hang in there for another month or so and things will calm down. The first three months are the toughest. Do you have a sling or baby carrier? If not, get one. I like soft-structured carriers like the Ergo and Beco best (they are kind of like the Bjorn but have several important differences that make them more comfortable for both you and the baby). You should be able to find a wrap-type carrier in Japan on the economy and I believe there is at least one mom who is making slings in the military community. Wearing your baby can help you get things done and give her the closeness she needs. Check out www.thebabywearer.com or http://www.askdrsears.com/html/5/t051100.asp for more information on babywearing's benefits. My son is 20 months and I still wear him sometimes. Sometimes babies just need to be with you. Dad can try baby wearing also. Put the baby in the carrier and start moving. Within 5-10 minutes (or often much sooner) baby will calm down or fall asleep. You can also learn to nurse in the carrier. You may be able to lay her down after she falls asleep as well and if she still won't go, she can nap while you are doing other things. My son can nap anytime, anywhere in the carrier. Being so close to you makes a baby feel secure.
As for getting your baby to take the bottle. Use pumped milk instead of formula and don't give her a bottle when she is hungry or fussy. Nurse her for awhile so she is relaxed and not desperately hungry and then use patience and let her try the bottle. It may be more successful if your husband tries to give her the bottle. He needs to be very patient. Don't yell at her if she doesn't take it right away. Don't get tense or stressed. Stay calm so you
can help her stay calm. Just keep offering the bottle. Don't worry if she doesn't take to it right away. Repeated exposure for small amounts of time will usually solve this problem.
As for weaning from co-sleeping, my advice is don't try to get her to go from sleeping with you to sleeping in a crib in another room. Set up the crib/bassinet/Pack-n-Play in your room. Since you will have to get up during the night to feed her, you will get much more rest if you co-sleep or have the crib in your room. An Arm's Reach Co-sleeper is also a nice compromise. It attaches to your bed but gives her a separate space.
Some things to keep in mind:
1. Babies needs change as they get older. Don't think that just because she won't take a bottle now that she never will. You need to stay calm and work with her. If you fight her needs and preferences and then give in you are teaching her that she needs to fight for what she wants, security and attention from you. That does not mean that you shouldn't try to steer her towards taking a bottle or taking a nap without you by her side, but do it gently. It will be better for both of you if you go slowly ad gently.
2. The first few months are the hardest, but breastfeeding is worth it, especially as your child gets older. You can go more places with less stuff, faster than your bottlefeedng counterparts. You can soothe a hurt or stressed child quickly and easily and you are giving you child the best nutrition at the lowest price. You can do it.
3. Pumping takes practice. Make sure you have the right sized flanges. Think about or look at your baby when you pump. Your baby can get more out of you than a pump, so if you can't get much out, don't worry, it is not indicative of your supply. Also, you don't need much in the bottle to start with (half an ounce to an ounce). You could try pumping on one side when your baby is nursing on the other, both to save time and take advantage of your baby's work.
4. There are other ways that dad can be involved such as bath time, babywearing, tummy time, etc. other than bottle feeding. He can do these things immediately and he can gradually work with her to give her a bottle.
If there is a lactation consultant or La Leche League group or even just another experienced nursing mother around, talk to them for support and ideas.

Building on what Emily said, some people will tell you that carrying your baby will make her walk late or be dependent. Like Emily, I carried my son a lot until he was about 15 months old (I still carry him at 20 months just not as much). He pulled himself up to standing the day he turned 7 months and was walking holding onto furniture shortly after. He was running by 10 months. Babywearing acts like tummy time and provides security. When your baby walks has more to do with physical, genetic structure and personality. Babywearing is much more active and engaging than putting the baby in a carseat carrier or swing or playpen, all of which have their places, but are often overused.
