5. You are constantly worried and anxious
If you find yourself anxious and stressed out all the time for no proper reason, it may be because of the sadness you are feeling. Unhappy people often find their minds haunted by needless fears and unwanted thoughts. People who are happy are generally satisfied with their lives and can control their emotions better than those who aren’t. While it is normal to be worried or fearful about the future, happy people handle it calmly and rationally.
