I am on my period right now and I am facing some intense anxiety. Like last night I woke up with a strong overwhelming anxious feeling and thought immediately that "I have to go to the emergency room because I can't take it anymore!!!!" type of feeling. Does anyone else have this?

I missed my period last month because of the stress but I do remember the month before I faced something similar during my period where I would go to every health store and waste tons of money getting homeopathic remedies to calm me down. They never worked. Is this all because of hormones? I am on Zoloft 50mg for a month (started at 25mg for 3 weeks and just started 50mg last week) can it be that the Zoloft isn't working?
