Am I possessed or crazy?

I will be brief here, I am 42 and the troubled started when I was about 16. I was curious about everything and did not believe in maybe God or the Devil. I invited the devil into me as a joke. Strange things started happening but I never saw the relation to a demon at all. I started being very scared almost paranoid, I started to withdrawal from family and friends maybe normal. I started seeing ghost and shadows to which I was frozen with fear..Anyways I am sure you heard all this before. Fast forward a few years I married and had a baby, to which I was scared of her almost like I was seeing her as a demon of which I did not believe in. When she was 1 1/2 old I was raped by a demon in my sleep and if it was not a demon it was a hellish nightmare experience. I awoke and was hearing things again and scared to be alone. I also made gestures while by myself in the house such as talking strangely and grabbing my crotch and making gestures with my tongue at the mirror. Again I started to believe I was crazy but did not want to tell anyone. My husband was a very religious person and through him I started going to church and was baptized, but yet that did not stop the shadows or random thoughts or actions. I was raped again in my sleep but still did not think anything of it other than it was a nightmare and believe me it was vivid with details. I finally decided to command all demons out of my house and out of me, I did this without anyone knowing. I told the demons that I was a child of God and demanded them to leave my house because they could not dwell in a house of God, I rebuked them also. This went on for months and did not help I was still having the same issues. Fast forward a few years, now divorced and my daughter is 5 and now she begins to hear things and I had never ever shared anything with anyone. She hears footsteps and the sound of her door opening and closing to the point she locks it at night. When she was 12 I got a phone call from here while I was at work and she was in terror, that someone was in the basement hitting something and going up and down the steps. I rushed home but did not find anything to explain her terror. At this point I was not being bothered by the rapes or strange things and was getting better, but now she was suffering greatly. She had always gone to church and at night she would pray this. Dear Jesus please watch over me as I sleep and do not let any bad guys, or a fire or evil get me and protect me, I ask in your name Jesus. Amen! Why was she having these problems? Fast forward again she was then 15 and seemed to be better and then now I start seeing ghost.. really ghost and my new husband and I were canoeing down a creek and this area was impossible to pull a canoe out as it was very steep on both sides and you are committed for a three hour trip at this point. We looked up and 20 feet in front of us was two people in a canoe, we yelled hello and no response they were very strange looking. We paddle to catch up and they disappeared and to this day my husband who does not believe in ghost said it had to be and he cannot explain it. There was no way they could have disappeared. I have seen very many ghost and two very bright ones with yellow hair with a bright light standing over me at my window. I keep have vivid nightmares about hitler and a train. I hated history and to be honest never knew about the death train at all until I had a dream so vivid that I looked it up online. I am scared at night and afraid to sleep because I hear things and I always ask my husband to hold me tight and also did you hear that? The dreams are absolutely horrid. I am up until 4:00 A.M every morning and I am so tired I can't function at all. I have gone to Dr.s and they cannot find anything wrong with me. What do you all think the problem is, I am tired of suffering so much. Please anyone help me.
