Some of my suggestions for feeling better:
Make a list of absolutely everything that is bothering you, or
every task you have looming over you. Brainstorm; write down
all of them, no matter how big or small, in no particular order.
Then evaluate the list. In a list of tasks, the best question is:
What's the absolute worst that could happen if I just cross this off
without doing it? Can I live with that outcome?
Sneak off somewhere and masturbate. Office bathroom stall, wherever.
Treat yourself to whatever food item you consider "sinful" (unless you are allergic or addicted) -- especially the festive sorts of snacks and desserts that many of us feel guilty eating. Buy yourself whatever you'd want served on your birthday. Savor it happily.
Some other people's ideas for feeling better:
Comfort Queen (a commercial site, but rather sweet)
Fat Girl Break Down! (size acceptance is their focus, but it's very nice and happy-making in general)
Reasons to love your body as it is [from anti-ana LJ]:
According to 6,000 women's responses to an orgasm survey by Weight Watchers magazine (August 1995)...70 percent of fuller-figured women said they almost always have orgasms, compared to just 29 percent of thin women...Thinner women may be on covers of magazines and have a greater selection of clothes to buy, but in this arena at least, it's bigger women who come out on top. (Excerpted from "Learning Curves" by Michele Weston, Fashion and Style Director of Mode)
Researchers at Michael Reese Hospital in Chicago found that plumper women desired sex more often than thinner women. On scales of erotic excitability and readiness, they outscored thin women by a factor of almost two to one. To ask women to become unnaturally thin is to ask them to relinquish their sexuality. (Excerpted from "The Beauty Myth" by Naomi Wolf)
"The children came to a perfume shop. In the show window was a large jar
of freckle salve, and beside the jar was a sign which read:
DO YOU SUFFER FROM FRECKLES?
"What does the sign say?" asked Pippi. She couldn't read very well
because she didn't want to go to school as the other children did.
"It says, "Do you suffer from freckles?'" said Annika.
"Does it indeed?" said Pippi thoughtfully. "Well, a civil question
deserves a civil answer. Let's go in."
She opened the door and entered the shop, closely followed by Tommy
and Annika. An elderly lady stood back of the counter. Pippi went right up to her.
"No!" she said decidedly.
"What is it you want?" asked the lady.
"No," said Pippi once more.
"I don't understand what you mean," said the lady.
"No, I don't suffer from freckles," said Pippi.
Then the lady understood but she took one look at Pippi and burst out,
"But, my dear child, your whole face is covered with freckles!"
"I know it," said Pippi, "but I don't suffer from them. I love them. Good morning."
(Lindgren, 1970)
