While some experience depression as a continual state of sadness or increased painful emotions, some depression can come in the form of a state of numbness - a lack of feeling that weakens all excitement and smothers your potential to feel joy. Suppressing or cutting off emotions could be a defense against something you aren’t comfortable feeling. Many people who suffer from depression are actually masking a feeling of anger, turning their rage toward someone else on themselves.
Anger can be a hard feeling to accept, as from a very young age we are often told it is bad to be angry, that we need to behave, and not to throw tantrums or get in fights. While acting abusive is never acceptable, feeling anger is a natural part of our everyday lives. By acknowledging and accepting or discussing your angry feelings, you are much less likely to turn these feelings against yourself or allow them to lead you into a depressed state.
