Why do I still suffer from such anxiety???

It's been a long while since I've had to be on here. Since then I've gotten a good job, gotten married, and am starting to build a house. How is it that I still suffer so much with anxiety? In the last 10 hours I've had about 7 panic attacks. Why is this? I have a great job, loving husband and family, and a roof over my head. I should be worry-free but sadly I suffer each and every day. It gets so much worse during my menstrual cycle too; so for 3-4 days I'm an even bigger basketcase than I usually am. It's exhausting. I hate it. Why can't I just be normal?????
