But that has inevitably taken its toll, leaving her feeling "tired and drained".
"I try and hide my struggles from them... but my daughter did say to school the other day, 'I'm worried because mummy hasn't been eating dinner with us and there's not enough food to go round'," she said.
"It's a lot of stress. I've got four children, I've got to manage, keep on top of and I've got to worry where I'm going to get our next meal from."
A 50-year-old woman who gave her name as Tracy said the food bank has been a "lifesaver" since she began coming in November.
"My cupboards were completely bare, I've been having one meal a day, just waiting until my tea every day," she said.
Faced with a crisis that is only getting worse, Feed the Hungry, which runs Coventry's 14 food banks as well as its international operation, has launched a range of projects aimed at helping people to cope long term.
A project to teach people to cook and make the best of what they have available is under development.
A "Pathfinder" project offers people the chance to buy food worth £25 ($30) for a small fee, giving them back some choice and "dignity" while at the same time offering them help to access grants and unclaimed welfare payments.
"It's working, the only issue that we have is that demand far outstrips what we can actually deliver," said project manager Hugh McNeill.
People who come through the charity's doors have "no financial resilience whatsoever, they've borrowed and they've sold everything they've got", he added.
"You can go right round the country and it's exactly the same in every city and every town."
For Wester-Okiya, hopes of building resilience are a long way off.
