NCd for this.
I'm feeling awful and helpless. I'm due on my period and once again I have feelings of intense anger (rage!). For background, I am 32 years old, several stone overweight and not currently on hormonal contraception. I've been feeling angry all day, and things came to a head when I snapped at my partner for taking too long and not answering me when I offered to help him with something. I called him a few choice words, turned off the computer at the wall and stomped upstairs like a stroppy teenager.
I'm now laying here in tears wondering why this happens to me once every couple of months - it truly feels like I've been taken over by a different person. I just want to throw things, swear like a sailor and storm around (although obviously I restrain myself from violence). I'd consider myself a gentle and happy soul and a good partner generally. I feel so guilty. Are these severe mood swings just part and parcel of PMS/PCOS? I also suffered from intense rage as a teenager and regret many arguments that I put my parents through. I really don't want to have to do this again. I'm at my wit's end. 
I guess I'm just after some advice on steps to take to stop these mood swings, and to see if anyone else out there has experienced similar. Thank you 🙏
