What is commonly used to help a friend with depression?

Support : When a friend has an illness, it is best to be a good support system for them - but not in a smothering way. You may also want to educate yourself about depression. There are support groups for families/friends of loved ones with mental illness. Nami may be a good resource for you. Here is the link for your local nami in columbus :http://www.Namiohio.Org/.
