When you are raging-fever, can't-get-out-of-bed sick, but you HAVE to get out -- and cook meals, and help your child use the potty, and, well, PARENT.
Poverty. Getting "options" like: (1) stay in school forever and "live" off grants and loans, (2) ignore your desire to SAHM and try to work, despite being unable to work past 5 (daycare schedule), or whenyour child is sick, so you get fired in favor of a more "reliable" employee.
The price of dating. The emotional issues, ugh, the expectations that we leave our super-momness at the door when we go out in order to focus on some infant in a man's body, and paying exorbitant babysitter rates for the privilege of deciding we prefer our own/child's company.
Knowing the contents of all the Christmas presents because *we* made/bought and wrapped them all, for our child. Nothing for us.
Hearing the crappy, defensive-at-best, accusations-of-immorality-and-stupid-choices at worst, stereotypes of single moms out there.
Questioning one's own feminism: "crap, maybe it *is* worth shacking up with some guy, just for his income and a little companionship."
Hearing "I'm practically a single mom" by a married person having a bad day, and it still being illegal to strangle her.
Waking up in the wet spot. And I mean the "doggone diaper slipped again" kind, not the *good* kind of wet spot.
