I finally have my TTT tomorrow

If I’m being honest I’ve cancelled 5 times already out of fear because I have really bad health anxiety and hearing other people’s horror stories made me even more terrified. There’s a part of me that wants to cancel again since I’ve been feeling horrible lately but I know I need to get it done, I don’t want to put it off any longer. I want answers to figure out how to improve my quality of life because I’m tired of my symptoms negatively affecting my everyday life. I keep telling myself that if I become very symptomatic it’ll be okay because I’m being monitored in a safe environment and 40 minutes of suffering is worth the diagnosis. With all that being said, I’m packing a bag to help myself recover after the test. Does anyone have recommendations? I already have salty snacks, vitamins, ice packs and water. Also my boyfriend is driving so no worries there.

If you’d like to tell me about your neutral/positive experience, give me advice, or words of encouragement that would be greatly appreciated! I understand people have traumatic experiences and even though you are completely valid, for the sake of my mental health please don’t share that with me. Thanks in advance!
