This is actually one of the beautiful things about snakes as pets. Your BP doesn't care if you don't play with it, doesn't need walks or playtime, doesn't need brushing or nail trimming. It only needs fresh water, a clean and proper environment, and food. All of these needs can be met at a minimum of 15 minutes, twice a week. Taking an extra day or two to clean the enclosure won't immediately result in scale rot, and a day late on feeding isn't going to cause starvation. Focus on taking care of your family, and just reserve a few minutes a week to take care of your BP's basic needs. Life will settle down eventually, and your BP will be no worse for the "neglect".
