In general, there are two types of treatment. One is psychotherapy, or counseling. The other is antidepressant medication. Psychotherapy with a well-trained therapist can help you look at the problems that bring on depression. It can also help you find ways to relieve the problem.
Therapy can be short term or long term.
You should be sure you feel at ease with the therapist you choose. Psychiatrists are the only mental health professionals who can prescribe medication and treat physical causes of depression. If you opt for trying an antidepressant drug, talk to the psychiatrist and your primary care provider about side effects, including how it might affect your blood glucose levels. Make sure that the doctors will consult about your care when needed. Many people do well with a combination of medication and psychotherapy.
