Dear Grey Matter,
Be comforted that you are alive and have survived chemo and have a T that is on your side.
Being denied is usually what happens the first time.
I don't know you or your circumstances so I don't know what you filed for.
You can pm me and advise you from there.
The whole process is confusing. You said that you were unsure if you filed the correct way.
Christina is correct you can apply for SSI, this is for people who do not have enough credits and have limited income.
Have you applied for unemployment? Temporary disability? Workers comp?

You will need a letter from your doctor stating your name age date of birth.
The dates of illness/injury with an dxs.
The reason why you can not work or go to school at this time.
Also include any emotional problems you have or have been treated for, including childhood trauma.
Sincerely,
Happiedasiy
Hang in there, things will improve.
