I’ve struggled w anxiety my entire life and I’ve been in therapy, on/off of various meds, and it just seems like no matter how much I can repeat that my thinking patterns are irrational, I can’t stop being anxious. 
For example, I can barely fly on a plane anymore simply because I am convinced it will crash, and take-off has me shaking and crying. Nothing I do prevents me from feeling this way and it interferes with my life so badly. I also have hypochondria and it manifests in cancer fears. I’m 26. When I was 23 I noticed a dimple in my breast when I lean forward. Went to the dr, had several exams, go an ultrasound, and it’s all clear. 3 years later I’m 100% convinced the dr’s missed something, even though no further changes to my breast have happened. I also have so many unrealistic expectations of myself. It’s so hard to function when I’m paralyzed with fear about making mistakes. 
What’s been a struggle for me is my sensitivity to medication. I tend to get all the side effects. Are we all just doomed to be in a constant war where we are rationalizing our anxious thoughts and still be emailing horribly anxious? there was a time where I hoped it would get better the more I educated myself or the more “evidence” I had that my fears were irrational but nothing ever helps and it’s exhausting.
