It's what I call a "Catch Fuck You".

- I need to go to the chemist today to buy period supplies and Dolased.
- I can't get my butt out the door because I'm in supreme pain from my period.
- To be able to go out to get the pain killers and period supplies, I would need those very pain killers.

Ergo, I'm stuck at home needing pain killers. Hopefully my Dad will go get me some. Until then, supremely hot heat-pack and lots of swear words.
