Melanoma metastisized to liver and lungs

I recently received confirmation that spots on my liver and lung are from an original melanoma tumor that I had removed in October 2009. I was 36 when if found the original spot. It was stage II level IV and had spread to one lymph node. That node was removed and benign. I have had routine scans every three months since. In September of 2011 the spot on my lung appeared. In December there was no change to that spot but a new spot appeared on my liver. March 2012 brought significant growth to the liver spot, a new liver spot and the original lung spot doubled. I am now 38, a wife, mom of three boys and scared beyond belief. I am trying to stay positive, but most of the information I have found on the internet is not promising.
My doctor mentioned several treatment options, the most likely IL-2. Is there anyone out there that can shed some light and hope???
