Help with seizure medication

This is my first request for monetary help and I hope the last. If anything in this request is incorrect or in appropriate I will gladly correct. I’ve run out of Keppra 20 days too soon. I’m $43 short because my insurance won’t take my co-pay because it is my oversight. Not sure how I ran out but it won’t happen again. I have MS and the Keppra is essential. I have enough left for 2 days. Any assistance would be greatly appreciated. I have CashApp. I may have Venmo but I’ve never used it. $toddyistheway
