Dying Marine Veteran

My brother Phillip who is 36 yrs.old a Marine Corp Veteran, is in critical care in the ICU on life support with Liver & Kidney Failure &  a host of other life threatening issues, I'm his only sibling & only immediate family member besides his 10 yr old son who is autistic,  I desperately need to fly out to see my brother & be by his side, doctor's aren't sure if he will survive since he is so critical, but I'm a single mom who has a 10 yr. old daughter & can't afford to fly out there & with no family or friends in California to stay with it will be very costly to stay out there to be with my brother, who really needs me. The thought of him being all alone with nobody or family by his side is unbearable. My brother Served in The Marine proudly has done several deployments shortly after 9/11 he got out & was suffering in silence with PTSD, the thought of my brother going through this all alone is hard for me to deal with when all I want to do is be by he side, especially if he doesn't pull through this, please help me to get to my brother & to be able to stay with him for as long as he needs me to be with him in his time of need. He is such a great guy who goes out of his way for others before ever thinking of himself. Please help....Thank You
