I am also a Christian (my husband is a pastor). I am also reading Joyce Meyer's " Pursuit of Peace" book. I just finished up, " battlefield of the mind" and it was really good as well.
I recently ordered a book from a Christian author who overcame panic attacks and anxiety from Amazon.com
It still hasn't arrived but as soon as I start reading it, I'll give you an update and let you know it's worth getting.
I think the scriptures are key.. I am memorizing as many as possible and I find myself repeating them (and saying them outloud) when my anxiety hits. I also pray through my panic attacks and it does seem to help.
It's tough to understand sometimes why God doesn't just snap His fingers and heal us miraculously from this, but I imagine it's because some how through our stories, we will reach more people and be a witness of His faithfulness.
So until I am totally healed, I will just keep trusting in Him and know that no matter how difficult this can be, I can do all things through Christ who gives me strength.
We must press on until we press through this!
