I don't want to ruin the Christmas season for my wife and daughter.. As corny as it is, how do you get into the spirit of the holiday season?

I am 29 years old with 10+ years of pretty solid work history. I have been a member of the Army National Guard for 4 years now and am nearing completion of a bachelors degree. I have, however, fallen into a bid of financial hardship and in spite of the previous stated, am unable to find employment. I apply for at least 4-5 jobs a day, often more. I am not an unintelligent person and I have good work experience and qualifications, but the few responses to my applications I have received have all been denials. I am getting very stressed and just thinking of Christmas or the holiday season makes me sick to my stomach. In spite of the negatives I mentioned, I am lucky to have a great, loving wife and a beautiful 1 year old girl. I don't want my failures, inability to find a job and financial troubles to ruin things for them. So I need you reddit. What do you do or what do you think I could/should do to get more into the spirit of the season and not make these holidays miserable for everyone around me?
