It was a typical Sunday here in Coimbra. Bright and sunny, I’d walked from the local train station through Choupal Park, to Centro Hipico de Coimbra – the stables – for my turn with a friend’s horse. I spent a lovely hour or so there, and walked back through the park to the station, as I have done several weeks in a row. It’s about four miles round trip. But I’ve become joyfully accustomed to walking long distances and up and down hills daily. No big deal.

I sat down for a moment to wait for the train. When I stood, my vision went all black at the edges. I fully expected it to clear, I was waiting for it to clear. Instead I came to up through a sea of concerned faces. I’d fainted. My first question was, “Did I miss the train?” I wanted to know how long I’d been out. None of my saviors spoke any English, however. I believe one of the older men was a physician; he was wonderfully calm, took my pulse, checked my eyes. He and his wife helped me to stand. He kept a hold of my hand, taking my pulse now and again, sort of folding my hand into his soft, strong, warm one.

I wanted to marry him.

The trip to the ER revealed nothing. Vital signs normal. Not enough water, perhaps. Or I hadn’t eaten enough breakfast. Or maybe the day was hotter than I was used to. There was nothing to be done. They sent me home with a package of biscuits and a container of milk.

I took a bus. An unfamiliar route. Got off too soon. Had to walk kind of far.

Belatedly, I noticed the back of my head was sore and realized I’d clunked it on the cement wall.

Over the next 48 hours I grew dizzier and dizzier. I recognized the sensations and symptoms. Several years ago I suffered a very bad concussion – a wicked fall off a horse. I was concussed again. And time is the only cure.

My being – and staying – in Portugal largely depends upon my staying healthy and independent. It has been a troubling two weeks. I haven’t been able to move my head, much less work. Or take walks. Or do errands. On one or two days, I was so dizzy and nauseous I couldn’t so much as listen to music. It made me sea sick.

In the middle of this, one of the two very young kittens I only recently adopted died.

Linda and Vince, the friends mentioned in earlier blogs, have brought in groceries and offered daily encouragement. So I am not alone.

But the specter of vulnerability, of dependence, of not being able to walk where I want, or where I need to, of not being able to work, has descended from an abstract place floating somewhere over my head to one sitting just there, in that chair.

I feel better today. I was able to write at least this. I’m encouraged. But will I ever leave my apartment with quite the same confidence? What caused the fainting in the first place? We don’t know. What if fainting is a permanent part of me?
