I have experienced anxiety/depression for the last 3 years. However, the anxiety may be persistent and last all day for 3 or more weeks, then it will be completely gone for another time period, then come back, etc. I am a 42 year old female and wonder if this is due to perimenopause? It sometimes corresponds to my menstrual cycle, somtimes does not. I am taking hormones to help this, but still experience it. Just wondering if this was a normal pattern for anxiety. Thanks!
