My mother has a life threatening thrombosis in her sinus cavity when she was four that caused her head to swell up to the size of a basketball. She was given last rites, but she survived despite the limitations of medical knowledge and the available pharmaceuticals in the late 1930's.
Thirteen years ago right before my father died, she had an angioplasty and then a stent and finally bipass surgery. In the subsequent years, she has also had stent place in some arteries in her neck. She's also had some occlusions in those arteries despite the stents.
What she's learned in the last 13 years is that she has probably had a lipid disorder for her entire life. The prognosis was questionable, but right after her first procedures, the drug Lipitor came on the market which almost immediately brought her cholesterol under control. She has several other medical conditions that also complication things, but the cholesterol problem has been largely under control.
My husband has been on long term disability for a year and a half. He was approved for SSDI in January retroactive to last July. The payment is not a whole lot compared to what his income was. Luckily, he had long term disability insurance and had paid for the highest level of coverage. The disability insurance payment was reduced by the amount of the SSDI payment, but the SSDI is only about 1/3 of his total payment and the total payment is only 60% of his gross income while employed.
One of the benefits of the insurance is that they paid for a company to pursue his Social Security claim. You can hire an attorney to work on a continency, which means when she is approved and receive her disability lump sum backpay, the attorney with take a percentage as compensation.
The application process can mean a wait for one or two years for the claim to be processed.
I would not think that working in a dry cleaning company would enhance her health, and the exposure to the chemicals may actually be doing her some harm. If she has blockages in her legs, standing all day cannot be good for her.
If you or another family member can take her in for a time, she can reduce her expenses and she may be willing to help you raise your children.
The new Social Security is not like the old Social Security. Even on disability, they encourage retraining and provide some flexibility in the amount of earned income a recipient can make without affecting the benefits. They have a program called Ticket to Work which helps folks to re-enter the workforce at whatever level they are able.
