Mom's Cancer battle is not good.

Hi everyone. Sorry to ask but we need your help. This happened so fast no one is ready for it. My mom went in to the ER for a cough on june 27th and was told she has stage 4 lung and bone cancer. Well that was a shock. We rushed to TX to see her and be there for this. We were there for 2 weeks and had to come home. Well they told us we had 8 to 11 months. Well she can only stay out of the hospital for 6 day before she gets so sick she has to go back. Well today made day 6 again. And the Dr. Put her in the ICU this time and have let us know she does not have a good chance to get out this time and if by the grace of God she does she will not make it out the next time she comes back. My mom has been through a lot and today she expressed how much pain she is in and she is preparing for the end.
Well we are not ready for that just yet. I would really love to get there and spend some time with her and my family before. Mom and dad just made it to there 51st wedding anniversary and i know this is killing him. I really want to be there and help with everything. So I am asking for your help!!!!
