I used to get more depressed over Christmas season and I called it "The depressing time of the year." I was told lot of people get depressed during the holiday. Let's see why they would, they have all this shopping they need to do, all these cards they need to send out, worrying about if someone is going to like your gift or not, deciding on what to get people, working out your budget, going into debt because you feel obligated to buy presents, being unable to pay your rent and all your bills because you just had to blow out your budget on gifts, people thinking logically and not buying anything because they can't afford it and then they feel bad for not being able to do it. Families or friends getting upset with someone for not getting a gift from them even though that person couldn't afford it.
Yep if people would lose the shopping and the card greeting or quit caring what people think of them, it take so much stress of their backs and they be more happy during the season.
