If you are experiencing severe aches and pains in your joints and muscles, creepy-crawly skin, killer headache, and general fatigue and nausea, you probably have a virus of some sort. Do Not, Under Any Circumstances:
expect anyone to help you
ask anyone to cut you some slack
try to get any other family members to take any responsibility for your children
think you can take it even remotely easy
expect your husband to feel sorry for you
assume your SIL will get off of either the telephone or her fat ass to grab the children when they're in danger.
feel excessively sorry for yourself
bitch about it to the Internet at large.
