My family doesn't believe in mood disorders. They think that it is just something that a person can use as an excuse. My family knows that I'm bipolar but, I still get told that it's in my head and that there is nothing really wrong with me. As a matter of fact, I'm living with my sister for 60 days (20 down so far,YEA!) and she has been tryig to get me off some of my meds and gets mad that I'm depressed! It can be a tricky decision to tell your family. I wish I wouldn't have because I knew how my family was before I told them. Is your family open minded about things? If so, I would tell them. They can be a great resource if they are understanding.
