Sometimes it may be temporary, like the death of a loved one. Other issues may be long-standing, such as a pattern of consistently choosing an abusive partner. At these times, working with a qualified therapist can help immeasurably in reclaiming your life. This is the most difficult step. If you're not sure what to expect from therapy, check out The Consumer's Guide to Psychotherapy by Jack Engler, Ph.D. and Daniel Goleman, Ph.D. for answers to common questions.
Different problems have specific approaches to treatment.
Check the phone book for national professional associations, such as The American Psychiatric Association. They will provide referrals near you, and can match you with the kind of therapy that will be most beneficial. Also check with friends, relatives or leading figures in the field, such as the head of psychiatry at a local hospital. Self-help organizations are another good source. For example, Alcoholics Anonymous would most likely know someone in the area that specializes in therapy related to alcohol abuse.
