feeling alone

Hi guys
My name is Marion and i am from Luxembourg.
I had my first panic attack 1 year ago and tried several methods to get rid off them. As you can imagine, none of them worked. My mother and my close friends are al trying to help me but none of them know how I feel and what I have to go trough, how hard it is for me to sit on a table with lots of people talking without getting anxious, to go out in the city without feeling anxious or even sometimes to talk to anybody. My panic attacks started really bad: shaking, crying, hyperventilating, crispations. During my therapy, I had all of these symptoms except of the crispations. 
It's been a month now where they have gone worse and if someone talks to me during a panic attack, I get hysterical and I can't stop...
I've tried out so many therapies and I know everybody I talk to wants to help me, but it does't because they don't know what to say as they never went trough...
I found this forum today and I hope to meet some people going trough the same kind of "problems" I do, as it starts to ruin my social life and even my studies (I had a panic attack during my exams and nearly failed it because of it)
I hope to get a repsonse, as I feel this would really help me :)
