Happy Birthday to you, you are not alone in not remembering how old you are, I to have to double check although I do tend to guess under not over my age. After that I am very thankful to have made it to 58. I mean what the alternative, not good.
I would like to give my 2 cents about SSI, you do need a paper trail, it really helps. I also recommend a SSI lawyer, I applied the first time without one and was turned down flat. I found a lawyer who only does SSI, the thing is, at least in Maryland, the lawyer wont take your case unless they think they can win. They only get paid if you get paid. My lawyer was great, he got me back pay, pay for my youngest daughter who was 17 so I got a check for her for a year, he enrolled me in medicare and then sent me $2,000. that the SSI people had overpaid him. A very honest man. He did all the leg work, met with me the day before the hearing, told me what to say, what to answer if asked certain questions. Less than 2 weeks later I received an award letter, a very large check for myself and my youngest daugther.
So good luck to you, definetly need to start the process ASAP. Take care and again much luck to you, please remember, this is not a hand out, you have worked and paid into SS for you entire working life. And believe me, you will not get rich on the amount you are awarded, you deserve every penny. If anyone dares judge you, tell them to walk in your shoes one day, just one day, they wont be so quick to judge then.
Take care,
Kat
