What Pact Was Made, Why Do I Have To Pay

It all started I think around like 5 or 6 years old... We had a little cocker spaniel named Dixie that we picked up randomly like she was a stray. Everything was fine for about the first month or two, until she started growling outside my window around 2:45-3:30 every night. Within the month she developed cataracts in both eyes making her technically blind! Well things escalated she went from growling to fighting every night at the same time 2:45-3:30 every night. This continued until she died about two years later. When she died I moved out live with my mother. I have one full blood sister and something started tapping on her window every night at 3:00 on the spot until 3:03 and would stop, she'd hear a scream then everything was good until the next night. My sister moved out and moved in with friends a month later. Well a few years goes by and we think were home free, guess again. I'm twelve now and I wake up to my window opening by itself one night! I was horrified! I ran to my mothers room and my window slams shut on my way out. The next night I'm scared to go to my room alone but nobody believes me on what happened the previous night before. I reluctantly go to my room that night and purposely leave my light on for obvious reasons. I wake up sometime around 3 AM to my light exploding and screams all around me. I try to move but I'm frozen with fear all I can do is cry. The next night I refuse to go back to my room so my mother let's me sleep on the couch. I wake up and can see a clock this time it reads 3:07 am, I awoke to my door opening and slamming shut multiple times. Nobody else woke up. The following night rolls around and my mother makes me go back to my room and sleep again. That night I awake again to the sounds of screams except instead of being frozen I'm held down this time I just knew I was on the road to possession but something just laughs in my faces says a few words in my ear and I don't remember anything else that happened that night... Needless to say I awoke with a bloody hand print smeared across my chest. My mother finally believed me; she's the one who seen it first, on my chest that morning when she came into my room. She called a physic for help. The physic showed up to my house and as soon as she opened the door she turned around and stepped off of our porch and said there's nothing she can do this pact has already been sealed. She left without another word... I was tripping I thought that I was going to die for sure... My mother decided it was time for us to leave the state so we moved to SC. The last night in the house me and my lil brother ran a quick check over it to make sure everything was locked up and secure like windows and doors well we finish everything and we are on our way out when all of a sudden we hear footsteps running towards us! Willie my lil brother was in front of me I'm in the back and I take off running so does he I shove him out the door and something grabs me from behind by my shirt collar and pulls backwards... I fight to get out the door which is less than a step in front of me! Willie grabs my hand and pulls me, shirt rips and me and willie hear the most blood curling scream you could ever imagine. Imagine a little girl giving a high pitch shrill but at the same time a huge man letting out a deep hollar, put them together and you might just begin to imagine what I heard... Well I'm 22 now and guess what its happeing all over again except this time it's coming for blood I believe. It's been a few years since I have encountered anything paranormal except for the occasional dreams that come true but they do it all the time now so its nothing new to me but like 2 or three months ago I was nearly drowned in our bathtub cause the drain gets clogged and water goes down extremely slow. Water builds up and when I'm ankle deep and I drop something in the water I have to pick it up and that's usually when it happens... Its like I get pushed from behind and help under water at least my mouth and nose are, but right before I pass out I'm literally let go. I don't know what to make of it what should I do and am I doomed? Did one of my ancestors make a pact with something and I'm the one paying the debt? What's wrong with me?
