Trying To Understand Myself

I have had similar feelings since I was young. I have never really knew what they are but I have always been drawn to paranormal things. I sometimes feel tightening and great throbbing in my heart chakra and when I am around ill minded people I get vibrations through my body I have helped friends identify many bad boyfriends. The strongest vibrations I have felt in my life were with my ex-stepfather, when I first met him I would get chill and vibrations. When he kept coming by before he married my mom I would become sick and my heart and stomach would hurt me. I told my grandmother I did not trust or like him. They ignored me. 4 years later he has not only hurt me but my mother and sister. He was a bad guy and I knew this all along. I have always been a good judge of character and sometimes it can be hard because I can become very overwhelmed and I just become overly emotional. There are time when I will be watching someone in pain or sad and my heart and solar plexus tighten and my childhood asthma symptoms start to act up again. Some of the worst places for me to go are hospitals. I cannot be inside them long become my head begins to hurt, I become nauseous and my breathing shortens. Its really painful sometimes. Its hard to explain. I want to know more about this and how to help myself.
