Let me get this straight.
You make $7.40 an hour, are disabled, and a full-time student.
Do you actually pay any net taxes?
If not, why should you get any "extra income" (as you like to call it)?
I'm disabled myself and your allowed to make money with a part-time job up to a certain amount, the more you make on your part time job though, the less you get in disability, it's been awhile since I knew what the amounts exactly where but I think it's something like up to $3000 you still get your full disability, anything above that you get less & less in disability.
Now I don't have any part time job so I get my full disability, which actually isn't all that much since I became disabled at 19, so I had only about 3 years of working to put into Social Security, but I'm getting $250 from the stimulus package which I'm grateful for because when the Bush stimulus happened I didn't get any of that.
