SSBN_Trident,
That is lousy. I am sorry they apparently did not look at your records and consider how your condition obviously impacts your ability to perform your duties.
Asking for reconsideration is the route to go. Hopefully, they grant a hearing and do a better job next time around. I am sure you aware that if they don't the danger is administrative separation. Keep us updated and we will try to offer whatever help we can.
I tried calling to see if you could help on the professional side.. I left a message.
