Frustrated & Stressed

I applied for disability on 05/1/2012; I was denied in August. I immediately applied again and I was denied in April 2013. I requested an appeal in April 2013. I have waited 14 months so far only to  receive a letter stating my request for an appeal has been received, this is June 2014. The letter also states that I will be contacted for my hearing date which could take several months. So now I am waiting for a hearing date. Truly unbelievable.
