I think that's a perfectly reasonable reason for you to have a gap in your career, and prospective employers should be understanding of that.

It is something you should be prepared to explain at an interview, but I don't think it would cause any problem.

You're right that it doesn't really count as experience. Employers won't necessarily mind a one year gap on your CV, but if you do find it difficult to get to the interview stage, it could help to add a short note to your CV explaining the gap. But I'd hope that wouldn't be necessary.
