@suesam I understand the anxiety associated with that biopsy. I have been in similar situations with tests looming in the distance. I'm going to suggest what I do. It doesn't remove the worries that accompany anxiety but it can be calming in the moment.

1. I remind myself that my worries are normal under the circumstances. Do I like anxiety? No, not all. Can I accept the anxiety? Yes, that's what I tell myself. My anxiety is present for a reason. It got my attention and so now it's time to let it go at least momentarily until it arises again - and it does. The more I do this skill of reminding myself that my anxiety is normal under the circumstances the more "normal" I feel.

2. I write my worries into a notebook to "get them out there". I figure out which of these worries are rational under the circumstances and which might be irrational (catastrophic thinking). An example would be writing a worry that the biopsy will show I have cancer. That's the worst case scenario and is an example of catastrophic thinking. I can't possibly know that. What I can know is that the endometrial biopsy may show nothing or it may show something. What are the reasonable possibilities?

3. I write what I am grateful for. In this case it could be that I am grateful I have a doctor who is taking me seriously and is following up. I am grateful that I have the resources (insurance) to see a doctor for this test.

Do any of the suggestions I have made speak to you?
