LONELY
Many people celebrate Christmas by themselves today: because they have no friends or family, because they are in an institution, because they have a bad relationship with their family, or because they are working all day. With the world constantly reminding them that it is supposed to be a cozy time of togetherness, they often feel lonely. Consequently, suicide rates run high in January, just after all the holidays. So today and after the holidays, contact someone you haven't spoken to in a while. You might help out more than you think.
