How to deal with fear?

Good evening,

first of all i'd like to thank you all for all the information about glaucoma.

I have few questions.
1. How do you manage with stress and how to deal with fear? My eyes are my greatest weakness. During medical tests i was sweating, my heart was beating hard, and i almost fainted. I was really ashamed becouse i am grown man.
I was told that my IOP is to high, and i know that my grandad has glaucoma so i guess i am going to have it too.
I am afraid of other tests, i am getting really nervous when i think about that so according to information on fiteyes my IOP is getting higher.

Can I get some sedatives before medical tests. How sedatives influence on IOP?
