I need $5,000.00 to repair home

I will be 74 in 2 weeks. have end stage emphysema, congestive heart failure and atrial fibrillation, and am on oxygen 24/7. I am on low social security, alone with no family or kin, no savings. need to have roof repaired, floor repaired, and need 6 windows and 2 doors. I had to drop my home insurance, and don't think i can afford the  minimal auto insurance on my '87 plymouth k., so may not be able to drive. I also need around 400 for real estate taxes.
Any and all help gratefully appreciated.
I can make it the rest of the time. just the repairs are so expensive. The county opportunity council checked, replaced my fridge (the old one worked) replaced my hot water heater (the old one worked) insulated the attic and fixed the a/c. said that was all they could do..To me, these were of no help in getting comfortable, because I can't use a/c...some windows won't shut, and doors have cracks or missing jalousie parts. couldn't afford electric anyway. 95 degree heat is almost intolerable.
This house is a small woodframe, built in 1945, and is very difficult to keep warm, cool or dry,
I have no tv, satellite or cable. My Social Security income is below the poverty level. I cannot reverse mortgage home because of poor condition. I cannot work at a job, not even as a Walmart greeter. I have pared my electric usage to the bone, even to turning on water heater twice a week for one hour, for 4 days of lukewarm showers each time. I use one ceiling fan, one electric light, one refrigerator, and try to keep usage of my well water pump (no county water) to a minimum. The washing machine and dryer, circa 1981, are both either malfunctioning or broken. My one extravagance is my 6 hour day electric usage of computer (free isp, dialup). I read the daily news online. I have a telephone, but no long distance service. I regularly buy my groceries from scratch and dent places, including my pet foods. St Vincent de Paul supplies my clothing. I use the microwave for cooking nearly all the time.
I had lung cancer surgery 2 years ago. Now, nodules are showing on both lungs. Pulmonologist has a wait and see attitude. Still too short of breath most days to do much of anything. Really cannot see a light at the end of this tunnel.
So, if you can see your way clear to help make it a bit more comfortable for me, you will have my gratitude.
