There are other options besides the bottle that can be used tomorrow while you are at work. They can feed your baby via dropper or a cup. It's messier, but get the job done without the nipple confusion.
If you do decide to stick with the bottle then have them feed your baby in a more upright position instead of in the classic cradle hold. Make sure that the milk is in the nipple but that your baby has to suck the milk out and that it isn't just pour out.
Once you have your baby home strip him down to his diaper and take off your shirt. Spend as much time skin to skin as you can (a baby carrier like a ring sling or wrap is a GREAT way to achieve this). Allow your baby to have free access to the breast. Not just for food but also for comfort suckling. Not only will this keep your milk supply at it's best but it will also reinforce to your little one that nursing means he gets all the warm, loving mommy snuggles he needs. House work can wait at this point. Do the minimum that you need to in order to keep things running smoothly (put wash and dry a load of laundry but leave it to be folded later, use paper plates so there are few dishes to clean, etc.). Or better yet find someone that can come over and help with your household chores.
You can come back from this so try not to stress. A stressed mommy makes for a stressed baby and then no ones happy. If you need to, take a nursing vacation starting after work tomorrow. Tell your DH that he can handle arranging dinner and that you'll be spending your time in bed with your baby reestablishing your nursing relationship. Your son is still so young and switching back and forth is going to be a little difficult on him. Don't give up though and before you know it he'll have gotten used to his new routine and will be back to nursing like a champ!
