If i am constantly scared of death and losing my mom, Please read i really need help!?

what's wrong with me? I am constantly scared, i am always thinking back to dreams that i don't remember having until that moment, and its like i'm seeing how i am about to die or how my mother is about to die. We aren't in any type of dangerous life, but i am so scared that i am going to lose my mom that i start calling her just tio hear her voice. I get so scared when she has to come home late, and i have a HUGE fear of going over bridges, the dark, and mirrors. I have a family history of depression, but i dont i have that, unless its a diff type. Why am i so petrified? I've gotten to the point where i a in tears because my mom's not answering the cell, but it'll be tht she's driving or in a meeting or soemthing, but i'm always imagining the worst. I wanted to speak to a school counselor but i dont want them to put me in a psychiatric hopital and i don want word to get out in school and everyone to start treating me like i'm a crazy person. What to do, and wht'a wrong with me?
