Need Help With Bills and financial expenses

As most of you know I have a ton of medical bills and debt. 82,000 dollars almost in bills, tricare nor the VA will help. By the looks of it nor the state as I've been trying to get on disability for the pass 2 years. I am a mother of 3 beautiful children and nothing is more important to me, than being here to watch them grow.  I have been through Chemotherapy treatment and the appointments along with the medication is costing me so much. My credit cards are at MAX. I also have other medical problems such as anxiety/PTSD and anorexia and  Crohn's disease.  At my current state, I am 122lbs and 5'11, underweight and i can only stand for 15 to 20 minutes at a time. Which brings up my next medical problem. I have to have another surgery to fix my tale bone because it's like sitting on a sharp rock. Which makes sitting sometimes impossible and I have to lend to the side. I cant keep canceling the appointments because then I'm not getting the treatment needed or medication filled.  There are days I cant hold my 5 month old son because my body is to weak and my arms just wont allowed it. I dont have any body fat left on my body to keep me warm, so I'm always wearing a jacket in 90° weather and I sleep with a heated blanket as well as 3 blankets and a beanie on at night.  I want nothing more than to get better, to wake up every morning like I did before and spend time with my children. This month has been the hardest I cant make our rent payment or any other payment because my medicine was alot more this month than last and disability hasnt gave me a final answer yet.  I dont like asking for help, I'm a big believer of if you want something you work for it and be a go getter. But I'm not able to be that go getter because of my health. So I asked this with tear filled eyes, anything helps.. I dont want to be homeless nor put my children through that. One heart to another, one vet to another vet, if you cant help than share.. Help me if you can I appreciate everything more than you know...
