Help me...cry for help?

Since i was little I have experienced a lot of paranormal activity. The first one that comes to mind happened when i was six. I can remember walkin past my mother & friends seated at the table playin cards,towards the stove to get some mac & cheese. Then walking back into the room and closing the door. I recall watchin some toons and then crawlin towards the edge of the bed,setting the bowl on top of the t.v. I then crawled towards my pillows leaned over and switched the light off. I got underneath my covers and slowly drifted off to sleep. I awoke to the feeling of falling off my bed. I looked around and tried to grab ahold of the sheets but i could feel it pulling me under. Then i was halfway under and a bright white light happenend. I was back on my bed...that was when it started. Then i went to live with my dad all hell broke loose there. I remember sitting on my bed late at night staring at this dead girl across the room, and she would dare me to get up and try to turn the light on.(I was twelve at this time) Then when i was sixteen It got bad...i would hear mirrors break...go look at them and nothin was broke. It would get freakishly cold. This stuff happens werever i go. I can feel a presence all the time watchin me. Anybody i date they feel it too. No lie. They will vouch on it. Since halloween is my birthday i went and spent the night with my boyfriend that night...and things went flying across the room he would yell at it to leave and it would get worse. Lights would flash off and on...but anyways these are a couple examples i could go on and on. I have woke up repeatdly not being able to breathe. Also i have had frequent nightmares.. They are usually like were a demon is trying to possess my family...also two nights ago...i smelt pure SULFUR in my room at three in the morning..
