Male PMS

I had to think for a little while about posting this, but in the end I decided that even if one person agrees with me or feels the same, it would validate my own feelings.  (Not that I need my own feelings 'validated', but you get the point I hope...).

I'd like to know if any other males go through an emotional cycle on a monthly(ish) basis. Yes, I know, some of my more low brow friends and acquaintances will now be shouting "gay!" at me, and wondering if I'm going through a trans-gender procedure but I can hold my hand up and honestly say I think I do go through this.
There has been some research into this - for example in 1929 a researcher carefully followed the moods of 17 men and it showed that they did go through an 'emotional cycle' every 4 - 6 weeks - however, I can only speak of my own experiences, and maybe see if anyone else out there feels the same.

I can't pinpoint the exact start and end dates of these feelings, but I do know that periodically I start feeling quite low, sad, fed up, bored. There is no cause, it doesn't happen because of any particular event, and quite often there isn't a lot I can do about it until the feeling passes.  Sometimes it lasts a day or two, sometimes nearly a week.  These feelings in themselves shouldn't be destructive in any way, but for me they bring on periods of self reflection and I tend to focus on the negative things in my life - which combined with the previously mentioned feelings make me feel even worse.  The logical part of my brain knows that I am very lucky in some ways (health, home, son, loving partner, family & friends etc.) but during this period of maudlin introspection I can't see the value in these things and tend to think too long on the negative - failed marriage, weight issues, money problems, isolation.
I lose interest in social media, I find that I want to cut myself off from people, and nothing seems to keep my interest (reading, TV etc.).
The company of my son, the support of my partner, the communication with my friends & family can help alleviate some of the depression but at the end of the day all I can do is ride it out.

I realize I could be opening myself up to some ridicule with this post - but you know what?  I've been bothered by these feelings for too long and I thought it time I see if I'm not alone.

So I throw the question open to anyone who still reads this blog.  Men - do you get these feelings?  If so, are you confident enough to be able to post in the comments about them?  Women - do you know / live with any men who seem to get 'moody' for no discernible reason?

As always - peace.
