How can you avoid stress

Speak up. Not being able to talk about your needs and concerns creates stress and can make negative feelings worse. Assertive communication can help you express how you feel in a thoughtful, tactful way.
Ask for help. People who have a strong network of family and friends manage stress better.
Sometimes stress is just too much to handle alone. Talking to a friend or family member may help, but you may also want to see a counselor.
