I think you should've taken the 1,000 and had been happy with that. You shouldn't even had asked him for money. It's free money and you're the one who sounds greedy thinking if he had $20,000 than he should be able to give you $2,000 and that somehow you "deserve" it for being there for his appointments or whatever. It probably came across that you were there for him because you were hoping to get money out of it..like you have some moral right. If he wanted to give you money, he should've been the one to offer it to help you out rather than you going to him asking for it.

The only way you'll probably be able to make it up to your brother and get that relationship back is to admit you were wrong. Think of it this way.. If he didn't get any money..you would've had to pay off your student loans another way..right..

Money changes people on both sides. People who have it become tighter and people around them want it. You did exactly what he said was going to happen..once he got it..you "swarmed" to take it and get a share.
