2 year old with Cystic Fibrosis

My 2 year old son was diagnosed with Cystic Fibrosis at 4 weeks old, which is a life threatening disease dealing with the lungs and pancreas. Because of this diagnosis, I had to quit my job right away to care for him just before my leave was up. He is not allowed in daycare at this age because of the his immune system not fully being built yet. Because of his Cystic Fibrosis, even the common cold can be fatal to him. I have no outside help so no one to watch him or my 9 month old daughter for me to be able to work. We do get some government assistance, but it's no longer enough to make ends meet. Their dad is not involved hardly, and does not help at all financially. Basically I just need help before my kids and I are homeless. I am raising this money to be able to have about $600 extra dollars a month for the next year until he is able to go into daycare. It would still be a little bit of a struggle, but it would be doable. I don't have any other options at this point... your help would be much appreciated.
