A 2009 study from the Journal of the National Medical Association surveyed 300 men and women at a free health clinic in Buffalo, New York. They found that respondents with insufficient perceived social support were the most likely to suffer from mental health disorders like anxiety and depression. A good friendship requires a balance between individuals–one where the needs of each are met. Good friendships have a myriad of benefits, such as increased feelings of belonging, purpose, increased levels of happiness, reduced levels of stress, improved self-worth and confidence.

While good friends can help you through traumatic events and can even help you to quit a bad habit you’ve picked up, toxic friendships can leave you feeling drained, stifled, unsatisfied and often unequal. Friendships are unique because they are tied to so many aspects of your life–your family, work, hobbies. When you have a toxic friendship, these feelings can permeate all of these areas as well. If a particular friendship is isn’t meeting your needs, it may be time to reassess whether it deserves a space in your life.

Humans by nature are social animals. Our friendships can have a tremendous impact on our lives–which is why it’s important to make sure that they are leaving you feeling supported, understood, and happy.
