I suffer from depressive episodes from time to time. It’s a terrible thing that caused–and can still cause–selfishness, self-inflicted loneliness, unmindful actions, and awfully strong and uncontrollable feelings in my life. My episodes used to be extremely bad, but now bad episodes rarely appear.
You can’t stop bad emotions completely, and I don’t think it’s healthy (or realistic) to think that bad emotions would, or should, never come again. However, I think it’s important to remember that no matter how bad emotions may be, emotions are emotions; nothing more.
