The simple answer is no. Psychotherapy is not only for individuals diagnosed with a mental illness. The truth is, we all face difficult experiences in life that seem unmanageable at times. Maybe you're experiencing difficulty in a relationship. Maybe you've lost someone close to you or have been diagnosed with a chronic medical condition. Maybe you're having a difficult time adjusting to a new job or a recent retirement. Maybe you're struggling with addiction or experiencing financial stress. Maybe you're feeling anxious or depressed and find yourself avoiding relationships and experiences you used to enjoy. Maybe you're not sure what you're experiencing or feeling but have a sense that, "Something just isn't right."
Regardless of whether or not you meet criteria for an official diagnosis, psychotherapy can help you more effectively address problems in living and relationships.
