Hi I'm wondering since I don't make enough money and my girlfriend has cancer is there anything out there the can help us, I have insurance tru my work, can she still get medical, can other program help us financially?

Most areas of the us has something called "section 8' that can help with housing, there is often a waiting list and you have to live or move into an apartment that is qualified under it.
In most places if you marry they can be added to your health insurance at work, ( not all places allow that) but you will often have to pay their part of it, ( that can be several hundred dollars)

If you have not, you can make an appointment with a case worker to see what welfare you may qualify for.
