My mom and stage 4 bladder cancer

I’m sitting here in the hospital with my mom and daughter waiting for her discharge and waiting for pathology reports and a plan. In the meantime told to take her home and try to live normally until we get “the call.”
She has a great team but this all has happened so quickly. It was just Thursday and my whole families life has changed.
We have been told the cancer tumor in her bladder is 6.7 cm and does not appear to be a “usual” bladder cancer. It has spread to her uterus and pelvic lymph nodes. We are Christian’s and my brother is the Canadian missions Pastor so travels all over the world.
What do I do? How do I plan? My mind is in chaos.
Do I look up trials she may be eligible for? Start feeding her CBD, have her apply for disability etc?
She’s already met with her pastor, has her funeral planned out and I’m exhausted
Any advice would be so appreciated
