Before my IBS-D took over my life, I was not anxious or nervous about anything. I would jump out of bed every day, happy and ready to start my day. Have to drive to an airport at 7am? No problem. Start a 9 hour car trip at 2am? No problem! Be in a crowd of people with no toilet in sight? No problem! Take a romantic walk on a beach? Travel by airplane? Go out to a nice dinner? Take a rowboat out on a lake? Did it all without a second thought.
Now... the thought of having to leave a safe area (translation: available toilet) makes me nuts. And if it happens unexpecedly, my stomach literally immediately 'melts'. For instance, my dad was rushed to the hospital last week and as soon as I found out, I barely had time to make it to the toilet. And yes, of course I was worried about my dad, but my stomach reacted because I knew that I had to get in the car and get to the hospital.
I've tried anxiety meds but had such a bad reaction to them that I hope I never have to go on them.
So, yeah, IBS definately caused my anxiety!
