What's the likelihood that my Lyft driver's sob story was fake?

Took a Lyft from the Marta station to home last night after flying back to ATL. The driver was a baw from Houma, LA who claimed that he was temporarily living in ATL because his daughter has cancer and is being treated at Emory.

He proceeded to dive into this sob story about how he had to quit his job in NOLA to move up here to be with his wife and daughter, but his son still lives in their Houma house and he has to pay the mortgage and bills. He said something to the effect of being short on the past month's electric bill by $63 and he has to work all night in order to make at least that much by morning. He apparently hadn't eaten in a couple of days and hasn't washed his clothes for a month. Also said that he has nowhere to sleep except for the room at the hospital.

I obviously felt sorry for the guy and tipped him $10 after completing the ride. However, the more I think about this, the more I realize the possibility could exist that he was making up or at least exaggerating part of his story, especially about the power bill, in order to coerce a bigger tip.

Am I wrong for being cynical about this or do I have a legitimate gripe here? People will lie about anything this day and age for a dollar and it seems interesting that he brought all of this up unsolicited.
