I have been having increasing difficulty during pms. I am 34 years old. Have had 1 pregnancy and child was born healthy. During PMS I get very anxious where I feel shaky and like I am going to have a panic attack. My head has horrible pulsating headaches where I can't think or function until they go away. I also have mood swings that give me relationship problems with my husband. I feel like I am going crazy. I get very overwhelmed, cry all the time, and am very over dramatic. Sometimes when I hear myself I can't believe it's me that is sounding like that. High strung is an understatement. Light sensitivity and high pitched noises also give me really bad headaches. Peoples voices seem to make the inside of my head crawl for lack of a better way of explaining it. I also go from very hypersensitive with heightened anxiety to very lows of depression. My head always feels like it just got hit with a hammer and my stomach feels nauseated. I have much difficulty concentrating and at this point I usually go to my room and cry myself to sleep. It is getting more difficult each time I have a period. Also I usually menstruate 5 days but have now gone down to 3?? any ideas?? is this normal?
