However, many patients find a way to cope on their own, or they seek support from friends, family, or one of the many infertility support groups now available in person and online, while others need additional help. Referrals for short-term counseling are common – especially to increase coping strategies, or to provide help with making decisions (as patients face many choices during treatment). Patients who experience prolonged changes in mood or sleep patterns or who have relationship problems should seek a more comprehensive evaluation, as these may be signs of anxiety or depression. Specific types of psychotherapy may also be useful, e.g. interpersonal therapy (which focuses on improving relationships or resolving conflicts with others) and cognitive behavioral therapy (which identifies and tries to change unhealthy patterns of thought or behavior) can give relief to infertile patients suffering from mild to moderate depression. Relaxation techniques are also applied, e.g. mindfulness meditation, deep breathing, guided imagery, and yoga based stress management.
