Curiosity

Until recently I have never heard about Indigo children or adults but my mother watched a tv show and it sparked her curiosity and mine. I am Sabrina, a 26 year old female. From the time I can remember I have been really sensative emotionally, have had a strong affection for animal life, depression that has ranged from sadness to utter despair from the time I was 15 until the present time, I can't stand authority or stupidity, I have a bad bad temper, I have never been able to focus on things for very long so I never did to well in school, I have experienced deja vu, premonitions in dreams, have had encounters of paranormal activities, I have always had a strong feeling that I have a purpose but still to this day do not know what it may be, I am very creative in writing poetry, I have experienced voices calling my name, I am very good at knowing who and what a person is without ever knowing them, and I am a very solitary person.
I have experienced these things for as long as I can remember. There are certain few friends and family members I have a deep almost psychic connection to. I can think about my mom and she will call me or she will be thinking about me and I will call her. When my cousin or best friend is sad or depressed I feel it, I know there is something wrong. I've always been singled out as the black sheep of the family because my thoughts and feelings aren't understood. I was diagnosed as being bi polar and having ADHD this past year but I don't think their diagnosis are right. I've extremely sensative when other people in the house are being negative I notice that I am more stressed and strung out. It is weird that my mother brought this up to me because her 7 year old son, my younger brother exhibits all of the characteristics of being a Crystal Child so do a few of my other siblings. I am the oldest of 7 children my mom and dad has me and my younger sister. My dad remarried and has 3 girls and 1 boy with my step mother, and my mom remarried and has a son with my stepfather. The one strange thing is all of my dad's girls are the five elements Earth, Air, Water, Fire, and Spirit which is something that is strange to me. I don't know if the elements have anything to do with the Indigo/Crystal thing but I thought I would throw that one in there if anyone knows. My mother tells me that I am a dark miserable person whose thought process is completely out there. I've never felt like I belong, I've had a hard time making friends because people think I am strange, and I've always felt like I am an "Old Soul" so to speak. I've read a lot about it and it is amazing how much I can identify with every aspect of it. I think it helps me understand more about myself than I did. Also I was wondering if there is a dark side of Indigo Adults, such as being negative etc?
