Terrible Hormones

Ugh hormones! 😫

I’m 37, have had 2 children who are now 8 and 10 yrs old.
In the last year or two i have noticed my PMS symptoms before my period are horrendous! I am unbearable!! I cry, i am irritated by any little noise, i am angry and snappy, i hate everyone and just want to disappear! Its terrible!! I’ve also started to get acne in the last 3 months! Wtf is happening to me and my body????
I have been on antidepressants for about 5 years which helped but now for some reason things are turning to shit!!
Is this like a hormonal imbalance or something that happens in late 30’s??
Whats my first step to finding out what the hell to do about this?? I just cant stand myself and my own company anymore! I am sick to death of this happening to me EVERY DAMN MONTH!! Any advice??
