She believes she knows where her son's body is now, in a refrigerator truck outside Bucha's morgue. She is desperate to find an official to hurry the process of inspecting her son and issuing the documents needed to release him.
"I get worried, where he'd go, and whether I'd be able to find him," she said.
Once she collects his body, she'll need a casket. A casket equals a month of her pension, or about $90. She, like other elderly Ukrainians, hasn't received her pension since the war began. She gets by selling the vegetables she grows, but the potatoes she meant to plant in March withered while she was hiding in her home.
Her aging cellphone keeps losing battery life. She forgets her phone number. Her other son, two years younger than Vadym, is unemployed and troubled. Nothing is easy.
"I would walk out of this place because I feel it's so hard to be here," Trubchaninova said, sitting at home under a tinted black-and-white photo of herself at age 32, full of determination.
She recalled watching her television, when it still worked, in the early days of the war, as broadcasts showed so many Ukrainians fleeing. She worried about them. Where are they going? Where will they sleep? What will they eat? How will they remake their lives again?
"I felt so sorry for them," she said. "And now, I'm in that situation. I feel so lost inside. I don't even know how to describe how lost I am. I'm not even sure I'll put my head on this pillow tonight and wake up tomorrow."
Like many Ukrainians of her age, she worked without taking time for herself, determined to give her children an education and a better life than her own. "Those were my plans," she said, agitated. "What plans do you want me to have now? How do I make new plans if one of my sons is lying there in Bucha?"
The cemetery where she wants to place her son can be seen from Vadym's old room, where his canes are still propped against the door.
On Thursday, she waited outside the Bucha morgue again. After another long day without progress, she sat on a bench in the sun. "I just wanted to sit in nice weather," she said. "I'm going to go home. Tomorrow I'll come again."
Across town was the kind of closure that Trubchaninova wants so badly. At a cemetery, two 82-year-old women rose from a bench and crossed themselves as the now-familiar white van arrived carrying another casket.
The women, Neonyla and Helena, sing at funerals. They have performed at 10 since the Russians withdrew. "The biggest pain for a mother is to lose her son," Neonyla said. "There is no word to describe it."
Like Trubchaninova, they hadn't fled ahead of the Russians. This is our land, they said.
