They Know I Know They're There

I feel like I'm going crazy. When I was five, I never really thought about ghosts/spirits/paranormal-entities. It wasn't until I moved to my new house that weird things started happening. It was weird because, my friends told me my house was haunted first, and I asked them about it later, and they couldn't remember hardly any of the stuff we experienced. We've kind of grown distant, but that's not the point of this story. My problem is that the occurrences in my house seem to be targeting me, and I think it's because I'm more sensitive to it. The occurrences used to happen to my sister and friends (even my adult neighbors at one point), but now they only seem to target me. I'm going to try to focus on what's happening in my mind though, seeing as this isn't a website for ghost stories. Basically, I didn't really notice until I was about ten, that I could tell different things about the spirits around me. I've started questioning my previous assumptions, because things seem more clear to me now. It's kind of like I see it in the back of my head, like it's not really THERE in my vision, but I can still see it. We've done different investigating things to compare my suspicions which (always) seem to be right. There is a lady in white, who manifests herself as a kind of broken up white light. She was murdered right before her wedding (maybe 1890's 1920's). She is the biggest spirit I can make out, and she used to try to contact me a lot. There is also a darker spirit thing, that I don't know what it is, I used to think it just was sad, but I now think it might be violent, because I got scratched in my basement. However, I need to get to my main problem, so as not to bore you. I can feel the different energies of the spirits around me, sometimes even see them or fact about them in my head. I used to just get by it by sort of making my own energy really big, kind of pure and golden (I don't know it worked). But now things seem to have gotten worse. I think they know I can feel them, so now, whenever I'm home alone they scare me. There's little shadows, just a couple minutes ago I saw an orb. There's also noises (which are confirmed by my beagle), once my name was called. It's scary because it doesn't happen to the rest of my family, and since I can feel the dark energies, it really scares me. My parents don't believe me, and by this point I think I'm just going crazy! Is this normal? How can I control myself to not be scared anymore. I'm a busy person, and when the energy starts messing with my room (knocks, bangs, shadows) I can't sleep and it's ruining my health and grades. Please help?
