OCD Timing

Hi guys, I am curious whether anyone else has noticed their OCD coming at similar times in the year. I recently realised that last year I had a massive panic about the same fear I am worried about this year around exactly the same time which I thought was curious. I know some people say you may feel down mentally because the days are shorter and it is darker and gloomier but I am not so sure that's it as I don't really feel like that is the case as I still feel like the days feel quite long for being a UK September.

Anyone had a similar experience?
