I'm glad you became aware of why at least part of your feelings of irritability were happening. But I would feel very crabby if I had to deal with someone making me jump through the hoops your father is just to get money so I could eat!

It's good to plan for healthy, inexpensive meals, especially if you are on a tight budget and/or have diet concerns. But your father sounds a bit too much like a dictator in the way he deals with your food money. Can you talk to your counselor about this? Maybe she can give you some ideas on how to talk to your father, to let him know how stressful and demeaning his tough tactics make you feel.
