Financial assistance for a young cancer patient?

Does anyone know of any good financial assistance for cancer patients in Texas?

I have metastatic thyroid cancer (spread to lymph nodes, drs are doing an mri next week due to suspicion of it making it’s way to my brain), and am scheduled to have surgery for it on April 21st. The only issue with that is that the surgeons fee is due, in full, by April 20th. The total due is $2100.75, not including the hospitalization bills I’ll receive after.

I’m a 21 year old student who works part time for $12.50/hr, all my money goes towards my phone bill, electric bill, and about 1/4 of my rent (my boyfriend pays the rest). I don’t have $2100. I have no idea how I’m going to afford this :(

If anyone has any suggestions or links or any ideas how I’d be able to afford this please reach out.
