Nat, you are such a sweet person. I can see you wanting to get your Family things that they need, and I hope you are able to. Keep in mind that the Holidays are really about spending time with Loved ones, although I can see how this is a bit different; if it didn't seem so necessary that you get your parents a couple of household items, I would say "your Family will understand if you can't do presents this year". In your case, though, I might suggest checking out a nearby thrift/resale store.

Sometimes you can find flawless items, wash them, and viola, you have something great! My paychecks aren't that fat, but I still have a fabulous glass coffee table - it looks new, and I probably saved $400 buying it used (from Goodwill).

Fund raising: I think this is a matter of opinion and situation. I wonder how old you are, and if your parents would feel embarrassed, or maybe angry if they maybe don't see this situation from the same point of view that you do? I would just keep those things in mind when deciding upon creating a fundraiser. If you do, I really hope you're able to raise what you need.

Also, your sister's boyfriend being loaded does not make her "better". It seems like you are trying with all your might! Anyone can be pampered, but it takes good ethics and a strong sense of responsibility to earn your own. I hope your Family can appreciate what a thoughtful, great person you are!
