I have NC for this so nobody can trace my username.
I didn't use a food bank but I did eat really scrimpily.
I bought my first house when I was 20 going on 21, I had a massive falling out with my Mum, she gave me two week to move out, I had 3 dogs and needed to buy instead of rent to be able to keep them so wasn't in the greatest financial position anyway (I paid rent at home).
Luckily I had a small amount saved that I had planned to use on a 21st birthday celbration and at the time the government had huge first home owner grants.
Within 6 months of buying my house the job I had been in for a couple of years which had always had fantastic hours slashed everyone's hours. I lived out of town so the petrol alone was almost equal to an hours work every day. Because of the way they did it though we all had crappy split shifts so I couldn't fit another job in, within 6 months I was dead broke and struggling to pay all of my bills.
I am embarrassed to admit it but I used to buy the bags of dog bones for about $2 and go through them for any 'useable meat' before giving the bones to my dogs, buying meat was a luxury I could ill afford. I ate sugar on bread, veg from the discount fruit shops, cheap pasta, heavily discounted bakery items that I could pick up at the supermarket on the way home etc.
I am hardworking and responsible with money but sometimes circumstances don't take you where you think you were going in the way you think you will go. On the upside the down times give you empathy for those who are less well off than you. I will always offer to buy food for a beggar for example, as it is always in my mind just how easily that could be anyone's fate.
I luckily landed a full time job and caught up on the bills but that year or so was a real down point in my life, if I had of had children I would have swallowed my pride and used a food bank to make sure they had some decent food every week.
