Anyone know of financial assistance in PA.

I was diagnosed with Ovarian Cancer in 2008 and have undergone 2 heart surgeries and a heart catheritization. I have been unable to work since Feb. 2008 per doctors orders. I have applied for SSDI and am awaiting a hearing. I am having difficulting making ends meet. I get medical assistance and $90 a month cash assistance as well as food stamps. My 70 year old Mother lives with me and pays rent with her social security. After the rent is paid we barely have enough left over to cover our electric bill. I have been told it will be shut off in April. I have contacted LIHEAP and our local community action program who tell me I am income ineligible for help because of my Mothers social security however they are not looking at other expenses. They ask for copies of bills and rental costs but then do not take it into consideration. Moving is not an option because we live in one of the cheapest apartment complexes in our area. Does anyone know of anyone I can call to help in PA. Thank you
