"I have a fear of traveling, even though I do travel the what if leading up to it is brutal."
This is a VERY common fear/issue among people with anxiety, especially panic. ANYTHING that takes us away from our comfort zone and "safe place" (usually home) causes us immense anxiety, and like you said, the anticipatory anxiety can be a BEAR. I know that if we'll have a vacation planned, I'll worry about it the moment I know about it, up til the moment we leave. It's awful.
Of course, usually, once we're on the road, or have reached our destination, I feel much better, but it can be rough without a doubt. Definitely utilize your PRN anxiety med for situations like that. When we travel anywhere, I usually take my Ativan about 45 min before we're leaving and let my hubby drive the first leg of the trip. Also, anything that causes distraction is great too, portable DVD player with your favorite funny movie or sitcom episodes, crossword/word search books, games on a smart phone. When I get engrossed in those things, my anxiety level comes down a lot.
No matter how long we deal with anxiety, there are some things that stay with us no matter what we do. For me, traveling is a biggie. I can manage it well and have learned various ways to cope of course through the years, but honestly, even when my panic disorder is WELL managed, I still struggle with that at least to some extent.
You seem to have a lot of great insight into your anxiety, and it sounds like you have a good plan, trying an increase in your Paxil, and doing some more work in therapy to help better arm yourself with coping mechanisms. I also recommend picking up a book or two about anxiety.
They can be so helpful, and there are some great self help books on the subject. The one book I think should be a MUST for anyone dealing with anxiety is "The Anxiety and Phobia Workbook" by Edmund Bourne. It's set up very much like a text book, which allows for a lot of "hands on" work that is very very helpful! I'll post a link to a health page I also created listing a bunch of resources. You can look through there and see if any books may interest you. Knowledge is power!
