I'm mad my grandparents didn't lend me money
I don't think you can expect money from them. Why are you mad they didn't lend you money?
They were always on my back and telling me what to do all the time. They never let me do anything.
You aren't entitled to money from your grandparents. Maybe you can get some sort of job to have income for yourself. It would be more reliable than expecting money from them.
I was only asking, but I'm going to look for a job.
I think looking for a job is a great plan! Once you get your first paycheck and feel the independence of having your own money, I'm sure you'll agree.
