McGregor's interview, which aired this morning on Good Morning America, showed a mother who is still clearly trying to reconcile the death of her son, who she called "baby bear." This past Sunday marked the one-year anniversary of Monteith's death, which an autopsy ruled was caused by "mixed drug toxicity."
"The loss is horrendous," McGregor said in the interview. "Until three days ago, I couldn't look at a picture of Cory... So there's been progress."
She is still unable to speak about the night Monteith passed away.
But she did open up about her son's struggle's with addiction. She knew when he was only 15 years old that he had struggles ahead of him. At 15, "he did a code blue, and I think that was the turning point," McGregor said of an early overdose. "He had a lot of emotional things he was trying to figure out — lot of it was he really wanted a relationship with his father. I think when a child gets invalidated they keep reaching even harder. They want to find out why."
But Monteith had been working on overcoming his addiction problems. In March 2013, a few months before his death, the Glee actor had voluntarily entered himself into rehab for substance addiction.
McGregor confirmed that she is still in touch with Monteith's girlfriend at the time of his death, fellow Glee star Lea Michele. McGregor said Michele texts and e-mails her, saying, "She's hurting, too... you see the sadness. I know her pain."
McGregor thought her son was easing himself out of the Hollywood lifestyle. He had plans to buy a place in Vancouver, British Columbia.
"I don't think we have power to change the choices they're making," she added while speaking about the attempts to help Monteith. "I think with the kind of connection Cory and I had, if we couldn't prevent that situation, I don’t have the answer."
