Welcome, @as86. when getting a new diagnosis, it can be hard to even know what questions to ask. You've certainly come to the right place to find a supportive community. To get you started, I moved your post to thsi existing discussion:
- Essential Thrombocythemia: Looking for information and support
https://connect.mayoclinic.org/discussion/essential-thrombocythemia-1/
I did this so you can read previous comments and connect with helpful and kind members like @nohrt4me @1995victoria @nyjean @preacherswife1977 to name just a few.

As you have more questions, you can use the group search to find more discussions related to ET : https://connect.mayoclinic.org/group/blood-cancers-disorders/?search=Essential%20thrombocythemia&index=discussions

Have you been referred to a hematologist?
