Happiness is the death of the ego. If you want to remain a separate entity from existence as almost everybody is trying to do, you will be afraid of being blissful, cheerful.
You will feel guilty in being blissful. You will feel suicidal because you are committing suicide on the psychological level, on the level of the ego.
Still Want To Become Happy? Than kill your Ego.
Take Care and Keep Smiling....
