When coping with uncertainty, supporting relationship help  

1. our emotional state;
2. our resilience and our acceptance of ourselves;
3. how we interpret situations or events, so that we see them as more manageable;
4. our motivation to overcome adversity and strive toward our goals;
5. the adaptiveness of our responses to specific situations, such as  our coping strategies and our ability to learn from experience; 
6. our relationships themselves in terms of closeness, trust, and feeling loved;
7. our physiological functioning, such as improved immune response; and
8. behaviors that comprise a healthier lifestyle, like better eating habits and self-care and less substance abuse.
