I don't know what is happening to me
I'm 17 years old and i'm too nervous about school this year, because i have my finals. I study all day (most of times), teachers say that i'm too good than the other kids, and that i'll do well. But i'm still too nervous. I also had some panic attacks lately. 2 years ago, lots of things happened in my family (dad cheated, mom got crazy and depressed, sister got depressed and then a little bit crazy) and now things are calming down (somehow okay) it's just sister is a bit crazy (have said that she wants to kill herself) and i feel insecure and scared all the time, that i might lose people i love, or that she will may hurt me (she has tried). I even had problems at school with the kids some years ago. They were all making fun of me and i totally felt all alone all this time (wanted to kill myself too).
And this year, i was all perfect (except from scared). Everyone was telling me that i have been too good and that i have changed, it seems like i finally love my self,
but yesterday something happened. I suddenly felt like everything around me is fake. Like i'm alone in a dark place, and everything (people, things) around me are illusions, they don't exist. Their voices were getting louder and i was feeling all alone. But it felt like a dream (nightmare actually) and i got more scared than i have ever felt. It's like i'm dead or something, everything feels like they don't exist in reality. I feel too empty. I don't know what happened. I told my parents about this and they got really worried. I also had too many headaches and i was feeling too dizzy this weekend. I don't know what's going on. I know, i sound like a freak, i maybe am, but i feel too scared right now, and i don't know where to turn to.
