Medical bill

I am a black latina immigrant and I got covid tested in early December after being possibly exposed to the virus, and luckily it came back negative. 

However, a few weeks after I got my results I received a bill for the “doctor visit” to get the test done... and I really cannot afford to pay for it. 

I had no choice but to quit my job a while ago and I have no insurance and I really need to pay this off.

Any amount helps and will be appreciated.
