Hi (((Birdcrazy)))
I think you should apply. It never hurts to try.
I am on SSDI, I have been since I was 19 and now 30. I applied for both social security and social security disability. I was approved for both, but only received 1 payment of SSI. It is so complicated, but your doctors should back you up and help you in this process.
Good luck to you, and keep us posted.
