Hey Michelle .......
Please ask for and investigate for help ..... sliding scale or whatever else. I did just finish a post on the "daily" for you about cutting the cost of meds.
I feel for you. As it's said ... "been there - done that"! With the grant I received (mentioned in the daily post), it was based on income - but was not ridiculously poorhouse rigid.
I live on social security, a small part-time income and a small IRA distribution. I qualified easily for this grant .... so search. I know it's time consumming and can get frustrating ... but it's better than where you're at right now.
Lots of luck to you four.
Rob and Giz
