I have heard that often people will ignore emotions because they do not feel they are valid emotions to have (e.g. anger), and because they ignore or suppress the real emotion, it can manifest as other emotions and issues such as depression.
I have been learning to see that life has a full spectrum of emotions and feelings, and none of them are necessarily bad; but a lot does sort of depend on what you do with these emotions. Hurting others or creating more problems while in the middle of whatever emotion would be a bad thing. But to just observe the emotions and learn what brings them on, that isn't such a bad thing. Feelings are just feelings and are okay to have. A lot can be learned from them.
