Help in diagnosis?

Hi I am a 14 year old female and I think I have an anxiety disorder. I have taken many online tests and they have all come out saying I have one. Recently I have experienced some anxiety attacks, one being quite serious where I could barely breathe or think straight and my heart was pounding in my head, it was because I was going climbing and have a fear of heights.
I am generally quite a nervous person but recently it's been getting out of hand and if I am nervous the physical symptoms are awful. I also have completely irrational fears of things I know are stupid but can't control, and fear for health and for other people. Things that I think may have caused this are that I had quite an unpleasant childhood with my dad beating my mum and me and my sisters, and I've recently had a close friend's dad commit suicide but I don't know if these are relevant :/
I used to be anorexic and slightly bulimic and have self harmed in the last year but have stopped all of these, my anxiety is the problem now only I haven't told anyone because I don't want anyone to think I'm crazy :/ I would like to have counselling again but don't know how to tell my parents and I want these surges of panic to stop and I don't know what they are for?! Does anyone know what I have and think i should do about it?! :s
