That will give you some idea of what to expect.

A C & P for SMC?

I assume you are 100% now?

Can you tell us more?

On saturday? Go to it. Let the person know your disabilities/problems. Don't sugar coat them. Be honest and tell them all. If you have a partner, might be a good idea if that person goes with you, for support and verification of what they have observed regarding your symptoms. I hope you sent away for all of your complete service files/records including service medical/treatment records...the whole kit and kapoodle. Also gather any dr records, hosp ot treatment records and any buddy letters or those who can vouch their knowledge of your disabling condition or witness to the event you are claiming.

Be on time and don't try to suck it up and be brave and not tell them all of your issues, it will hurt you in the end. Get copies as soon as you can from medical records/information dept. Everytime you go for care or treatment get copies to make sure their documentation is correct. Calm down and let it all out to help you to receive treatment/assistance with your issues. Good luck.

How did it go?
