Caretaker, struggling and depressed.

All, forgive me if this is not the right way to post in this forum. I found the instructions vague at best, but please point me in the right direction if I'm lost. My wife was diagnosed with synovial sarcoma in her leg about 2 years ago. After the worst 24 months of our lives with aggressive chemotherapy, radiation, and surgery, she lost about a third of her upper leg but was cancer free. Now, after the eighth or ninth quarterly checkup they have located something suspicious in her lung that will require a lobectomy and biopsy. I am terrified. I know I have the strength to support her again and I know that I will. We have been married 21 years and she is my world but I am scared that I will break.
