Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.

As you have learned, .. it cannot be treated or managed by ONLY the depressed person. It REQUIRES a 2nd party ... a PROFESSIONAL (therapist, counselor, DOCTOR) and USUALLY medication. Without treatment, It is usually progressive and is VERY DESTRUCTIVE as you already know.
I have seen, in cases of marriage and both are diagnosed, either effective treatment for each or a divorce are the only ultimate choices. I urge you to get into an effective treatment plan from a professional .... and your husband definitely should also. Your mutual conditions will not get better, probably worsen, ... unless you both attain treatment.
