Help with medication cost

I have psoriasis and arthritis ive been diagnosed with it 5 years now its a painful itchy experience. My insurance covers 80 percent of my injection shots. But I had a few bills that came out and im short of paying for it exactly 85 dollars. I would be very blessed if there's anyone that could help because without my shot I become very limited in movement an it'll put my job at risk i can put my cash app info at the end. Thank you and God bless https://cash.app/$ccy1990
