'We always voted for Chavez'
For years, Venezuelans supported President Nicolás Maduro who, like his predecessor, Hugo Chavez, used the country's oil wealth to fund social programs. But when the price of oil began to fall, and the economy to falter, many Venezuelans started to protest the hand that fed them.
Mariza is among them. Her entire family supported Chavez. "We always voted for Chavez," she said, blaming both the former leader and current president for mismanagement of the country that led to this crisis.
In the past, "there was no hunger, there were no shortages, there was no separation," Mariza said, explaining that when things were good, you left the country "for a vacation, not for necessity."
The desperate needs of her family brought her here, to Cúcuta -- a border city with one of the highest unemployment rates in Colombia -- where she struggles daily to make enough to send food, diapers and basic supplies to her mother and kids.
If her mother found out what she was doing, would she understand? "My mom is a super mom. My mom is everything," she said, her voice cracking again. "And I know that the day she finds out, for whatever reason, it will hurt her but she won't judge me."
