I too am easily scared and have never really enjoyed haunted houses. Went to HHN once in 2017 and had a great time, but only braved 1 house and was terrified. I'm a UOTM this year and was able to do the TM preview on Tuesday. Without going into details, I would recommend giving it a try. There are clear barriers between most (but not all) scarectors and guests so if you pay attention you can usually see where the scares are coming from. That said, quite a few still got me (there's a few places with no barrier), but not so much that I was miserable. The scare zones are great but there is plenty non scare zones to relax in. I also didn't notice them getting as up in your face as they used to and in many places they are up on stilts and platforms. Also there's 2 shows that are excellent and not scary, plus lots of food and drinks. The rides are usually walk ons. And if you're a Harry Potter fan, Diagon Alley will be open and mostly empty with NO scary stuff at all (not allowed). I had a great time and can't WAIT to go back when it's opened to the public!
