Psychic Abilities Getting Confusing And Out Of Hand?

This is my second question on this website, but I feel as if this one is more important than the last. I began getting psychic abilities last year around this time and they have since grown tremendously, but have also become out of control.

I can feel other people's physical pain and tell them exactly what's hurting and how much on a scale of 1-10. I'll get the ailment exactly right which surprises them, but isn't good for me. I'm getting my mom's back pain because she has scoliosis. My grandma has severe health problems and I get her abdominal pain. My grandfather has trouble breathing and I often have shortness of breath. I always feel terrible because I can feel the pain of people I'm close to or in close proximity to and it's really wearing me down and I don't know what to do.

I get daily premonitions and know what's going to happen in the near future. But it's always something bad. I predict death, accidents, and just general bad things. These premonitions mostly come to me at random times that I have no control over, but on very rare occasions I can try to purposely get a vision. When I do that I'm left feeling dizzy, nauseous, and with an incomplete vision. I don't know how to control this and would like to know how to strengthen my ability so that I can get visions on command sometimes and not feel bad afterwards.

This is one of the things I feel is getting out of control and just. Weird and it's creeping me out and making me feel like there's something wrong with me. My dad's an alcoholic and we don't get along at all since I highly disapprove of his constant drinking. He's started physical fights with me before about his drinking, and I remember very clearly the first time this happened about 6 months ago. He pushed me backwards and raised a fist towards my face and was about to punch me when I got extremely angry, more than I've ever gotten before. I blacked out in the sense that I wasn't conscious of my actions, I was just seeing myself act and watching what I did. Keep in mind that my dad's about 200 pounds, 6'1, and pretty muscular and knows how to fight really well while I'm 110, 5'2, and pretty skinny and not muscular. I reached my arms out and pushed him back so far and so hard that he stumbled and barely caught himself before he fell. He looked so shocked it was almost comical, but then rushed back at me so I shoved him again, harder this time. I could feel the anger coming off of him in waves and felt like I was absorbing it into myself. He stopped after the second shove and looked at me like I just fell out of the sky and landed in front of him before leaving the room. I shouldn't have been able to shove a grown man that far back given my size. I can't even do a chin-up! It was like I was taking his anger and strength and using it for myself. How is that possible? I can't find an explanation.

Also on the subject of my dad, I think I'm somehow making bad things happen to him, but I'm not sure. When I get really, really mad at him he either has car trouble (a tire goes flat or gets a nail in it, car breaks down, etc.) right after we get into an especially bad argument or he has a bad day. He thinks I have people messing with him and his car but I don't and I'm not doing it myself- consciously.

And in my house, the people who owned it had a daughter around my age (16) who committed suicide by hanging herself in a closet in the house. This was sometime before the 1960's. Ever since I started getting psychic abilities strange things have been happening to and around me. I often have a ringing in my ears, and it's hard to describe but it feels like something's trying to get through to me but is just short of breaking through. I've had my ears checked multiple times and there's nothing wrong with them. I can sense a spirit around me and I feel negative energy from it, and I think it's the girl who died in my house and she's trying to get through to me. My cat looks at the air and follows some invisible thing with his eyes a lot, and when this happens I can sense the spirit but not see it. I've had heavy objects fall near me, the sound of clawing on doors (it's not my cat because he stays near me all the time) things bumping and creaking when they shouldn't and a lot more things.

I'm not sure what's going on and it would be great if I could get some help.
