PMS or PMDD?

I have PCOS and was not on birth control for many years until I got married two years ago. I was on Nexplanon for a year and a half. I’ve been BC free for a year as we are trying to get pregnant. That has yet to happen. Which could be part of the problem:

Anyways my periods are not very regular but I do have one every 35-40 days give or take so I guess more regular than they used to be. About one to two days before I’m supposed to start I get these awful mood swings. I’m angry, anxious, panicky, and just can’t deal.

Recent example:

My husband asked if he could go spend a Friday night and Saturday afternoon with his best friend about two hours away. I was honestly at the time totally cool about it even excited for some “me” time. Come Friday the mood swing hit hard and I’m feeling like he just left me behind and I’m just texting him crazy stuff like how could he leave me blah blah blah. I know. Serous batshit crazy.

Fast forward Saturday morning I’m apologizing because logical me knows how completely crazy I was being. Then I see that he’s also hanging out with some of our friends and I just lose it. I felt so incredibly left out and crying uncontrollably and depressed. Texting him and ruining his day then apologizing. Like who does this?? I’m almost 32 years old not 16. I know for a fact that what I’m saying to him is CRAZY and not me at all but for some reason at this time of the month I become an anxiety ridden psycho who can’t stop eating or crying.

Anyone else have this issue and what did your doctor do for you? Making an appt on Monday. I can’t keep doing this to my husband but I feel so lonely at the same time because I have no one to talk to that has also been there.
