Nervous about upcoming med test

My anxiety was already up, but it's getting worse because I'm nervous about a test I'm taking next Friday.

I'm allergic to aspirin and related drugs. Several years ago, my doctor advised me to go to a drug safety clinic we have here. They test drugs on you in a safe environment where they can treat you if anything happens.

I finally got an appointment to go to the clinic next Friday. They're going to test me for my reaction to Celecoxib otherwise known as Celebrex.

The doctor told me that 97% of people that are allergic to aspirin don't have a reaction to Celebrex. And the 3% that do react don't have a serious reaction, which means they didn't experience anaphylaxis.

I'm still nervous about it. Celebrex is in the same family as aspirin. The test is 3 hours long and they basically have me take a pill and then sit with me in case something happens. It's the only way to test. I asked them about a skin test and they said that doesn't work for this.

I'm coping by writing down all my passwords and sites that I use for banking etc. I showed my son how to get into important things like my mortgage, my bank and my email. I need to know that my family will be ok in case I have a really bad reaction.

On the one hand I know I'm probably over reacting but on the other, you never know how things like this will go.

I had a scare with my recent emergency surgery and want to make sure I'm prepared this time.

What do you think?
