Journey to no where?

I have been getting Social Security that pay for my meds and chemo treatments and keeps me alive. Today I got a letter that I have almost hit the maximun coverage for drugs and treatment. I am less than 900 dollars away from being done. But actually I am done....my chemo treatment costs more than 900 hundred and a months worth of meds ....My expiration date has been extended by the treatments....now they will be over. I am scared .....I am mad...I am confused. I don't have the money to pay for the treatments, so my journey may be coming to an end.....I am mad. I am scared. I don't know what to do.
