When really depressed I will just try to avoid any contact with people. I will do my stuff and then go home to watch movies and drink. I have sometimes been wondering if my hypomania is a disguised depression though. I get very energetic but also pretty irritable. My dad explained his manic states away with "just a reaction of the body to depression". But he also chased my question if he might be bipolar away like a fly. Anyway I can pretty much hide my depression from people around me.
