Help to fund my father's burial

In December of 2016, my father was sent to the ER at Harris Methodist in Fort Worth after becoming paralyzed in his legs, and had become confused and talking out of his head. After many tests at the hospital, an unsuccessful surgery to remove a tumor on his spine, and after a brain surgery to get a sample of a tumor they found in his brain, he was diagnosed with CNS lymphoma. It is a very rare and aggressive cancer that attacks the spine and brain. He received chemo until August of 2017, and was declared in remission. After that he went to stay at a physical therapy center to try to regain his ability to walk again. Dad had been making progress...until Early March of 2018, when he suddenly started losing what little mobility he had regained, and began talking confused again and sleeping excessively. All the exact same symptoms he had when he was first diagnosed with CNS lymphoma. 

On March 18th of  2018, MRI results showed that he had multiple brain lesions, and he had had a stroke. The CNS lymphoma is back, and due to how quickly and aggressively it came back, treatment isn't an option this time, and even if he got treatment, doctors said it'd only buy him another month before it came back again. On March 22nd of 2018, his oncologist estimated that he has 2 weeks left to live. She said he will eventually go into a coma and his passing will be painless and peaceful. He is at the therapy center on hospice now.
Words cannot describe the shock and grief we're all going through over this.  We're trying to sell some valuables, and my mom is starting a minimum wage job soon, but we have little to no means to bury him. We would be indescribably thankful for any help that could be given. Thank you.
