Yes. Mental illnesses such as Major Depressive Disorder can cause severe and permanent disability. You will need to apply for SSDI if you paid into Social Security and have enough credits.
I used a social worker to help me fill out the application online. Submit your medical records from your psychiatrist, therapist, and hospitalizations.
As far as I can remember, I was approved in less than three months.
It's not easy surviving on SSDI. In my case, I receive about a third of what I used to earn. My lifestyle has been altered significantly.
I hope you have supportive family and friends.

It took me about 2 years to receive disability with the help of a lawyer too.

It took me about 5 years with a lawyer

Yes,my job fired me because my doctor had restrictions on me,which made it easier.
