Cycles? Or depression?

I do things in cycles. I read this kind of book or that kind of book. Then for a while I write. Then I work out way too much for a while. Then I do something else.

I don't think it is as obvious as what my husband does. He goes through cycles, too. Survivalism. Programming. Writing. I'm sure there's another one, but right now I can't remember what it is.

Usually, though, when I read romance novels I am depressed. I've been reading them for the last two months. Sometimes as many as 20 a day. Sometimes as few as five.

I wonder if I am depressed. Thankfully I haven't been having any nightmares, another typical symptom.

It's just something to think about.
