How do I get diagnosis?

I want to feign Agoraphobia to obtain a diagnosis and apply for benefits. Why? I'm not sure. I don't even really want the money. I figure if I can get money for doing nothing I may as well.
It shouldn't be to hard for me as most of my family think I have this anyway I am not agoraphobic though I can relate to you somewhat as I used to be really shy, had my shyness persisted I probably would have developed agoraphobia thought It did not, I got bored of it, I got bored of everything and a little bit angry. I left school at 15 and became a Hikikomori (this is the best term I can find to describe my current situation, though I do not quite fit the stereotype), these days I spend most of my time daydreaming or else filling my head with nonsense that will likely be of no use to me, but so what, I'm the closest thing to 'happy' as I've ever been.
I've gathered that apgoraphobics experience anxiety when confronted with socially demanding situations, or even just being in public. For me I feel mostly disconnected in those circumstances however if I try to interact with them I get really angry and fixate on destruction(usually with fire, I like to burn things).
I've decided it's probably better I remain in my own world, without wanting anything and without trying to fit in because I don't and I never have. I could get a job but living off benefits would be easier so why work? I'll leave the few jobs there are to the people who actually want them Agoraphobia would be the easiest thing to fake so I'll do that. I figure it's only fair I tell you why I want to pretend and I understand if you are annoyed at me for doing this.
If you could please tell me about yourselves Have you got a diagnosis? What questions did they ask? What answers did you give?
Thanks

You should print this out, and read it word for word to your Dr.

Youll get your free benefits for sure.
