I agree with @Lento and also the other people posting here. Don't fight fear, you can't win, and even if you win, you lose.
I also suffer from anxiety attacks and I also had to learn this harsh truth. But actually it isn't harsh at all!
First you fight fear and you realize this only makes it worse, so after suffering enough, you let the fighting go and you accept the fear. Once you get used to that you start to surrender to fear. This is how far I got after my second to last anxiety period and it produced great results, I was anxiety free for a couple of years.
Last September I relapsed into anxiety so I had to go through this process again, luckilly I was able to do it much faster and just after a few weeks I was doing a lot better. But this time, I went further, and I also discovered Leo and this forum. The next step in dealing with anxienty is that you have to embrace it. Nature is chaos that is in balance, if there is an unbalance, Nature will correct...and this is always brutal! The same thing is true for your mind, if there is unbalance, Nature will correct and fear is the way it does this. The only obstacle to get back to balance...is YOU, you resisting fear. You must learn to love fear and super conduct it (See video of Leo about extreme emotions).
Right now, although the worst is over, I still do this almost daily, I look for my fears, I induce them, I embrace them, I burn through them, and I grow, like I've never grown before!
Best of luck
