That happens to me all the time. I often skip going to activities I normally enjoy when I'm feeling down. Like grizmom, it's generally because I feel like I'm not in a good place, and I expect that I would just be a drag if I showed up. I often force myself to go anyway, and I don't always enjoy it.

Here's what I think you should do though... let it go. What's past is past, and there's no point in beating yourself up about it. That will only make things worse. Cut yourself a little slack for being sick, and move on.

What's worse than being depressed? Being depressed and feeling guilty about something or other. I'm still learning love myself and to let the guilt go.
