Lather, rinse, repeat. I don't know if that qualifies as anything abnormal though.
I agree with Penny. It would be worth it see a doctor if it's possible for you to do so.
From what I was told by my old doctor and psychology teacher is that depression, in the shortest sense, is when common feelings like anger, sadness, loss, and frustration manifest for weeks at a time (or longer). In other-words it's being sad for a consistent long-standing period of time.
For me I've had issues with anxiety and depression since I was a lot younger then most people even get diagnosed (lucky Emmers) and when I figured out what depression and anxiety was the way I lived my life made sense and I understood why I was like I am. Sometimes I can go months feeling sorry for myself and like a lump of shit on a stick for no real reason or triggered by stressful situations. Sometimes I can go YEARS feeling pretty good. Depression isn't always a solid state of mopeyness. Sometimes there are good days and sometimes not so good days.
So it could be worth talking to someone about if this is how you're feeling.
