Try not to let things get to you as you formulate some kind of strategy for dealing with it. This is not ignoring it, but it's not being overwhelmed. You can create a source of social support. Talk to friends, family, coworkers to build a support network. There are organizations to help as well - Affirmative Action, the Employee Assistance Specialist at USU to help you not feel stuck.
Family members can serve as a haven in a heartless world.
Reality checks - conversations with your coworkers can provide a perspective that things aren't quite so bad, or point out our own involvement in the problem. Especially if it is an issue of fairness, social justice, or compassion. This is the time to talk. Don't go it alone. Think carefully before speaking.
