Pride is self-interest plus contentment, guilt is distress plus fear, and perhaps shame. All our affect responses and feelings are valuable in relationship, in clarifying values, and in self-defense. They are part of our survival equipment. Each can be handled in healthy and unhealthy ways. Learning healthy ways to use them to respond to life is part of growing in wisdom and skill for living.
Emotional growth is lifelong.
Maturity at any stage means being able to deal with what faces you adequately, not with flawless precision. The last thing anybody can afford, however, is to stop growing in emotional skills. Acknowledge openly to yourself your poor skills in handling this affect or feeling. You might remember what it feels like to be compassionate or forgiving to someone you love who disappoints you. The best defense against always being afraid is learning how to fear wisely what to fear, how to muster courage in the face of fear, and when to tell yourself there's really nothing to be afraid of.
