Jerman, I never had any problems with anxiety or panic attacks until after gettting diagnosed with Crohn's, specifically until I started Entocort. I started seeing a counselor who has helped me tremendously. Lavender is prolly the best thing in the world when it comes to my panic attacks. Its very calming, I went and got a million lavender things to put around my house! LOL I might have went a little extreme, but hey it helps me ALOT! She also taught me a breathing excersise, sit with both feet on the ground, take a breath (and always breathe with your stomach and not your chest..easiest way to make sure you're doing that is to put one hand on your chest, one on your stomach..move the hand on your stomach), hold it for a second and imagine a bright ball of light on your head (its all of your anxiety), breathe out and imagine the ball going all the way through your body, leaving through your feet, push all the anxiety out.
Last week when I saw her she taught me a tapping thing. Its too long to post here, but it helps as well. She said alot of soldiers with PTSD who have panic attacks swear by it. If you'd like I can get my paper out tomorrow and type it up and send it to you.
I know what you are going through, it was running my life for the last couple of months, but I'm making HUGE progress. I'm also cheating though and taking .25mg of Xanax in the morning. I'm allowed 3 a day and I only take one, so I think I'm doing pretty good. Also try distracting yourself and keeping busy, those 2 things seem to help me the most.
Sorry this turned out so long, but I hope it helps you somehow. And maybe Greg will have some more ideas that will help us both!!
I'm tired of it trying to take over my life, Crohn's does that enough on its own!!
Good Luck!!
