Any advice on how to continue with basic functions while dealing with depression?

I’ve hit a bout of depression and this time it got me good. I’m going between feeling emotionally flat or very sad. I’ve been in bed most of the day, listening to music, crying off and on over absolutely nothing. Things feel hopeless. I can’t find joy in anything I’m doing. I’ve felt this coming for several days but today was the big day. I tried making some crafts (which usually brightens my day) but I felt nothing. I just wanted to climb back into bed. I’m exhausted. I need to get up. I need to handle chores and other daily tasks. My husband continues to ask if I’m okay to which I reply, “Yep.” But I’m not. So here I am, because I’m not sure what else to do at this point. What helps you when you’re going through depression? I’m already on antidepressants.
