Single mother in need of medical bill help

My mother Martha Zavala has always been a hard working mom. She has always had the interest of her kids over her own as long as she's been a mother. She's spent the last twelve years working in an industrial laundry service in order to provide for her family.

About eight years ago she was diagnosed with a medical condition known as factor v leiden, It is a condiotion that causes her to form blood clots any where in her body. So she was told that she would have to deal with this for the rest of her life by taking various medications (blood thinners,iron tablets,blood pressure medicine). Her health has been up and down since than; But because of the medication she is on it causes her blood pressure to drop alot and get poor circulation to her legs. About two years ago she developed an outer skin ulcer on her left leg near her ankle. It started from about an inch wide and she has been dealing with it since. But in order for her to take care of her kids she kept working on her bad ankle against doctors orders because her kids well being was more important to her than her own. 

About a year ago that same ulcer began to grow and get worse over time. But no matter how bad the pain or how much doctors urged her to stop working it just wasn't an option for her. Who would pay rent,bills, and put food on the table? I have a job but on my own I can't pay her rent and mine let alone bills. So she has been working on a very bad leg despite the pain for the past year.

This is where my plea for some help comes in. Her leg has gotten very bad over the past three months so bad that I have had to force her to stop working and hope that the leg would get better. But the way it's looking the leg might take months to heal if it will ever heal. This is all so difficult for her because almost all of her past income was for bills and her medications. And with out a job you can only imagine the thoughts running threw her mind. But for her to continue to work on that leg in the condition it's in she will eventualy have it amputated and the long term outcome will be alot worse.

So I have moved back in with her in order to help her pay rent and bills. But recently got laid off from my own job so now I am working through temp agencies in order to maybe pay rent and bills but it's a struggle. It really is and I myself have been overcome with the fear of so many bad things happening from all of this going on in our lifes. 

All I am asking for from you the people that I know can be very genorous and giving. Is a little help for her so she can take what ever time is needed off in order for her leg to heal. Any help would be greatly appreciated. I wish there could be something I could offer in return for your help. But unfortuneatly  I can't. 

If you have taken the time to read this and I hope many people do I hope you find it in your hearts to help her out because her would right now is turned upside down for her and I can't even imagine what she must be feeling. 

Thank you and god bless.
