Hmm, normally I would say just give her a special rate if your instinct tells you to, but not for free. Saying that though, I treated someone with serious financial issues once for free, he was in agony with his back, and something wasn't right, couldn't figure it out what it was, but the pain was real, hospital had been no help, adn I felt simply compelled not to charge hima bean, even though he kept insisting. It made no sense, but I had to follow my gut instinct. Anyhow, I was deeply unhappy with a sense that there was seriously something wrong there, and eventually I got him to have a scan on his back that showed a malignant tumour in his spinal chord, something you can't feel or see. He got operated on and is now as right as rain. He was the person I thought I studied for, it was a compelling pull to help, maybe an old debt of sorts, but SO much good came from it afterwards, in drips and drabs, but it had a special feel. Sometimes things just happen that do not make sense in normal circumstances, and really in the end it's just down to how strong a feeling is about something. Good luck, and it's nice that you care.
