HI, I have been through the disability route and there are only a few disabilities (I have one) which are considered 'automactically' to receive disability payments. The disability procdure also automactically sends you one or more refussals of disability before finally giving it to you. So do not 'give-up' just because you receive this (these) refussals; it is the way the disability board does things!! No one receives full disability for a year, it takes that long to process it.
Your best bet is to look in the telephone book for an attorney who handles disability cases. The whole process is quicker and so much easier if you have a lawyer!! The lawyer will take a percentage of the check you recieve when case is settled. If you lose the lawyer gets NOTHING! and you owe NOTHING. There are laws restricting the amount the lawyer can receive, which is usually 1/4-1/3. The disability board will let you know what the lawyer CAN receive and you are to tell them if the lawyer takes anymore than what the law states.
The hard part is the full year without any income, so be prepared to support your father till then. I lived with my daughter when I became disabled and I gave her my check at the end of the year when my case was won to pay her back for taking care of me for that year. You could arrange this with your father if it will be hard for you to care for him for that time period.
Good luck. Jackie
