It's OK Sugar, vent away!
It always seems to me that state agencies are willing to help some of the wrong kinds of people and very unwilling to help those who want to help themselves, but just need a little extra boost. While teaching, I overheard one young lady (still in high school) admit that she was pregnant with her second child so that she could get more aid, and that her older sister had even more children for the same reason. Those are the ones who get aid quickly!
My daughter is going through the same hoops right now, since she finally had the sense to leave her jerk of a boyfriend, but she has the added complication of having a 4 yr. old son.
I don't know if it is possible, but is there any way to go "over the head" of that supervisor? Do you have any friends or relatives to help until the disability comes through?
Good luck to you, and keep us updated.
