Improving Intuition & Communication

Before, I was a different person and I didn't understand my abilities until I saw things for what they really are. When I was twelve, I suddenly was terrified of the dark, especially if I was alone. I of course blamed it on watching scary movies. I know things about my peers but can't tell them because I'm afraid they'd think I'm crazy. I don't really know these people but I feel their pain physically and emotionally. I sometimes see things that aren't there. For instance a blank sheet of paper can be in front of me and suddenly writing will appear in cursive or backwards or very faint, I frequently ask what they are trying to tell me but I don't understand. Sometimes they talk to me but all I hear is my name. I often mistake the voices for family members until I realize I'm alone. I was okay until I became depressed and everything changed. I became a new person after realizing that our desires keep us from reality. I felt "awake" and felt a bit more mature (I matured quickly at a young age). I have terrible migraines and don't get much sleep, but when I do I get night terrors & nightmares. I wake up screaming but I can't hear myself; or suddenly I'm unable to breathe; I sometimes wake up to someone watching me. I never feel alone. I don't understand what my purpose is, or how I can control my fear when I hear the voices. I don't know how to communicate with the voices or how to warn people when I know something is wrong. Please help me understand and improve the communication.
