Motes passed away in early February from an apparent drug overdose. She was 37.
"It's just heartbreak," she told the publication. "It's only been 20 days. There aren't words to explain what any of us have been through in these last 20 days. It's hour by hour some days, but you just keep looking ahead.
"You don't want anything bad to happen to anyone, but there are so many tragic, painful, inexplicable things in the world. But [as with] any situation of challenge and despair, we must find a way, as a family," she continues before straightening up in her chair. "It's so hard to formulate a sentence about it outside the weepy huddle of my family."
