I know there's a post about cycling on here already but I can't seem to find it at the moment so sorry if this is a bit repetitive. But I guess what I was wondering was if anyone experiences rapid cycling with their BPD. I've recently started tracking my emotions (a very in depth charts and graphs type tracking because I'm horribly nerdy like that) and it almost appears as if I cycle around every two weeks (give or take). I've only need tracking for a couple months now so it's nothing I can be completely confident in, but I do think it has helped me "prepare" for when I will be especially moody. 
So the main question is does anyone else have some specific characteristics of cycling that they've noticed? What are they? Also I've done a lot of reading on cycling but if anyone knows of any research done specifically with BPD an cycling or just some interesting websites I would love for you to share!!
