Depression, chronic pain and with crutches. "Accident" happened outside of US.

I was unsure whether to post this in the "Do You Qualify" forum or the "How To Apply" forum.

I am a citizen of the United States but currently in Argentina. A year and 4 months ago, due to non-diagnosed depression, I attempted to throw myself off of a building. I broke lumbar L1 and L2 (two bones in my spine). I spent 5 months in the public hospital here in Argentina and eventually had two surgeries to get a prosthesis put in.

I have been recovering for the last 11 months, and I have gone from a wheelchair to crutches. It doesn't seem like I will be able to walk without crutches at any point soon.

I did online work for a company after the incident for some months however due to my severe depression and excruciating pain I was unable to keep the job for very long.

I am constantly in pain (neuropathic pain) and am unable to stand for extended periods of times.

I feel completely unable to function due to my mental and physical problems.

I have two questions.

- Would I qualify for disability?

- How would I go about applying for disability when my medical record, history, doctors, psychologists/psychiatrists, etc... are all here in Argentina?

I am willing to go to the states to do the process.
