Help with travel expenses while I get cancer treatment

Hi my name is Brennan and I'm the proud parent of beautiful baby Birdy. Several months after she was born, I received a diagnosis for the mystery ailments that have been plaguing me for years. I have stage 4 salivary gland cancer. After several courses of radiation and chemo that have failed to prevent the spread and growth of the cancer, I am in a drug trial at MD Anderson Cancer Center (which appears to be working!). The cancer I have is very rare and MDACC has one of the few specialists in the country who study it. Being in the trial requires me to travel to Houston (a 3 hour drive from our home in Austin) every week and stay for 2 or 3 nights. We have maxed out all our credit cards and need help paying for my travel expenses.
