Is my house haunted it doesnt feel right!!!!!?

We bought a house in the country.. Eight acres ...at the end of our property there is a gravesight... I still have my house in the city but we were traveling here everynight and on weekends with our three kids on a weekend I had no kids we came out here and out of the blue I was laying in bed watching tv and my heart started racing when I got up I went outside and sat on the deck started sweating and my heart was pounding really bad... I got up walked into the house and completely collapsed I couldn't feel my limbs or lift my heAd I thought I was having a heart attack and that I was going to die I was rushed to emerg and was unable to speak to even tell them what happened ... I have had three episodes since but only in the country not my city house and just dint feel good when I am here ...the doctors say it is anxiety but I feel something different and think there is something wrong about this house ...when I walk into the kitchen I keep thinking I see someone standing there...It is only in the house my chest hurts anD I feel dizzy when I go outside I feel better???
