SAN ANTONIO -

If your Christmas isn't like the song "the Most Wonderful Time of the Year," you may be suffering from a case of the holiday blues.

Depression at this time of year is common for a number of reasons.

If you think you fall in the category of "seasonally sad," you may want to give yourself a gift or two to take away some of the blues.

One reason for feeling down during December? Money.

"I really don't have money for gifts for my nieces and nephews and that kind of upsets me," said Felicia Greg, a UTSA senior.

No. 2 may be having too much to do.

"It's pretty stressful," said Kiera Ortiz, a UTSA Junior. "(The) Christmas holidays, shopping and trying to get all the gifts together."

No. 3 is the family.

"We all have that dysfunctional, crazy family," said Samantha Watson, a UTSA Freshman. "Just kidding, mine's great."

UTSA Associate Professor Dr. Mary McNaughton Cassill says holiday bules and the fix is all in the mind.

"What I always tell my students is that stress is a gap between what you have and what you want," she said. "And what I think has changed in the holidays in the last 30 years is that the 'want' has gotten so much harder."

And her students get a double whammy because right in the middle of all the holiday hoo-hah and Christmas chaos are dreaded final exams.

"The place to fix it is in your head," Cassill said. "That's the mind part. So it's not to rush around and do more and more and try to make the holiday perfect. It's to think about what really matters, what your values are, what you want to do and to cut back those expectations."

More advice from Cassill: limit your exposure to media images of picture-perfect Christmas families; they are not real life.

Limit your alcohol consumption; it can act as a depressive.
