Possible TW; mention of vomiting 

Does anyone know any helpful tips to help me deal with this? I have never been good with heights and it has gotten much worse doing during this pandemic. I was watching the Lord of the Rings and during the scene with Gandalf on the tower, I started gagging and my whole body started getting tense. I have felt similarly, but not quite so bad. I couldn’t help it. It was horrible and I need help. Please, any advice will be welcome.
