I set up an interview for disability, anyone else done this before?

I set up an interview for disability, anyone else done this before? I have never had a job before, I am 24 years old. I have interviewed for dozens and cant even get my name out at the beginning because it takes like 5+ minutes for me. I just lock up and cant do anything. And I obviously never hear back from any of them. I finally had enough and am going to try to get SSI benefits. Has anyone with a stutter done this before? What was it like? The paper I got said it is supposed to take an hour(lol, good luck having me finished in an hour) to be interviewed for them to see what your disability is. Im actually kind of looking forward to it in a nervous way. It is the one time in my life where I want to get stuck as much as possible. Weird feeling.
