Scared its stomach cancer

Hello,

I know no one here can give me a definitive answer, but I feel the need to vent.

I am driving myself to distraction with worry over unusual symptoms I am having. I frequently have bad heartburn and take PPIs for it. A couple of weeks ago I started having 10 hour attacks, which eventually died down last week. But now has been replaced with nausea, stomach ache after eating on both sides and loss of appetite, I have lost half a stone because I just don't want to eat.

I had a H/Pylori test which was negative, but was taking PPIs, so make be false negative.

I have done what I shouldn't and have been googling and am convinced I have stomach cancer.

I have a horrific gag reflex so am paying for a Ultrasound rather than camera, the doctor has never mentioned a camera by the way, but I am booked in for a blood test.

How do you stop yourself from panicking and endlessly scrolling?
