I personally love that feeling and push myself through the house, but I have a few suggestions if you really can't take it.
- Covering your ears take a lot of the fear away from jumpscares in film and video games, and scares in houses are no different. An open palm over both of your ears will make the scares much more bearable if it's the audio that really gets you.
- If it gets to the point where you no longer want to experience the house, just talk to one of the employees in black hooded robes and they'll help you out.
Also, if you're with someone you know that you're comfortable with, jut push your face into their back. If you're taller than them, this one won't work, but it seems to help any girls I take that get really freaked out.
