What can i do to get over this once and for all?

I am a 24 year old healthy female. I have a perfect 19 month old and a wonderful husband. I get to be a stay at home mom which for me is the greatest blessing. Anyhow I have terrible anxiety. I've had it all my life. It comes and goes. I'll be anxiety free for months and then out of nowhere for no reason it's back. I've been anxiety free for over a year and for the past 2 months it's come back full force and of course I'm thinking oh it must really be something this time, but it's not. Two times now I've asked my husband to take me to the ER and he says no which is good because it would be a big bill for nothing. It's like I know I'm okay and that there is nothing wrong but I can't seem to shake this anxiety. I know if it was truly something I wouldn't be talking and walking around I wouldn't be able to function normally and where it is debilitating I'm still okay..I'm wondering what any of you have done that has worked wonders. It's time for me to stop this way of life and start living and enjoying.
