Dear PMS lady,
A few things to keep in mind over the next few days...
It's not really that sad. It's just a commercial.
If you must yell, do it alone in the car to no one but yourself. You'll be happy for that choice tomorrow.
You are the only one loosing sleep over how you treated people today. The women in your life understand and the men probably didn't notice. If they did, just be extra nice to them tomorrow. Men get over things more quickly than we do and won't hold it against you. Unless you keyed his car. He might hold that against you.
It's normal to feel like an emotional zombie.
It may seem like it's the end of the world because someone ate your dessert or your internet isn't working. Try to realize that these are not life shattering events. It's hard to put anything into perspective now but in a few days you'll see more clearly. I promise.
In the meantime, try to exercise, get plenty of sleep, enjoy hot showers, and for the love of God avoid all Lifetime movies. You will only sob realizing your love life blows. Plus, the fact that the pretty lady usually, always gets murdered will leave you fearing for your life. It's one of the few emotional roller coasters we can avoid this week.
