Wow. Sorry about your situation.
I like the option of samples from the doctor and about trying to lower the prescription qty.
But, the fact is, you need money NOW and nothing will change that.
I would go to a payday loan business with a store front, one that has been there for a while. I know some offer some specials for first timers, especially if the loan has a quick turnaround for repayment. You already know the interest will be high, and i am assuming your credit cards are already maxed out.
Do you have anything newly purchased? What about Christmas gifts for other people. Sometimes hard choices need to be made and i would return anything i could to minimize the payday loan.
You can always be sick and skip the Christmas parties to avoid having to give a gift right then. sounds like you could go buy the gifts next week and get by with noone knowing teh real reason.
Anyway, enough of potentially useless suggestions. Go to a payday loan business with a store front. At leat there is someone to talk to face to face.
I hope your future holds better options as you go get that missing college degree and make lots mroe money to avoid this type of situation in the future.
