Negative feelings have received a bad reputation, especially with the New Age philosophy. However, all your feelings are important. Your "negative feelings" are there for a reason. They let you know that you need to pay attention to them and they may signal that something needs to be addressed in your life. It's a good idea to keep a journal of these feelings to better understand their meaning and significance. Accepting yourself means honoring all your feelings.
