It may be the pill, or it may be something else. Has anything else changed in your life in the past six months? I would recommend that you go and see your GP to discuss this.
If anything, my life has improved over the past 6 months. Thats why its so confusing to me that I'm always so cranky and moody. I've gotten married to an amazing man who loves me and work has improved so thats not causing as much angst as it was last year. And everything else is as good or bad as it always has been. I'm definitely going to make an appointment with my doctor to discuss changing the pill to see if that helps.
