You wont know until you apply, Seems like you have enough work credits to be granted SSDI if its approved. Does your Doctors feel that you need disability? If they don't agree its very unlikely you will win, "most " people get denied first go around, you have to appeal.

The initial paperwork is annoying and alot to fill out, Loads of questions about your daily life .. How your Mental illness/ physical illness effects your daily life and your ability to work and support yourself, etc

Take your time filling this paper work out and be honest. They will also send you to have an exam by there own Doctors.

It can be a long process. I know some people get approved first try , I know some people that have to take it all the way to a court hearing. some people it has taken 2-3 years to get a court hearing , just depends on the back log of cases in your state.

You can apply online or you can go to your local Social Security office and ask for paperwork and information.

Good luck
