I have been suffering anxiety for the past 12 years, on and off or I should say, under control or not.
I see a naturopath as I didnt want to go on anti-depresants. She is fantastic and when I feel an anxiety attack building (usually from stressing about stuff) I take drops for a few days until it is under control. I dont know where you live, but she is in Blaxland NSW and I would highly, highly recommend her. If you want more details, just let me know.
I also did body balance/pilates/yoga to unwind. It was fantastic especially when I was pregnant (I did it up to 34 weeks).
And again, as previously mentioned, talk about it. I needed a few councelling sessions as one bout of anxiety was caused by a close family member dying thus bringing up my own anxieties about death.
And the best thing to know, is your not alone. Many of us go through this from time to time.
