LOS ANGELES, California (CNN) -- Anthony and Lisa Leoni have little time to worry about whether California's budget crisis will affect their daughter's life-sustaining care.



Anthony and Lisa Leoni are afraid of budget cuts that pose a threat to daughter Jessica's care.



A steady stream of nurses, caregivers and therapists visit 12-year-old Jessica at home around the clock. Jessica suffers from a rare and fatal disease called Niemann Pick Type C. A cholesterol imbalance destroys healthy cells in the liver, spleen and brain.



Although Jessica led a relatively normal life before the illness worsened, her mother always knew the disease would eventually take over.



"Jessica was playful, happy and loves people. My heart was always a flutter because you never knew how many moments you'd get," Lisa Leoni says.



In Jessica's case, a grand mal seizure suffered Memorial Day weekend 2005 brought a world of hurt to the Leonis.



At the height of her symptoms, Jessica suffered up to 60 seizures a day. The disease, also known as NPC, has stolen her ability to walk, talk, eat or even breathe on her own. An oxygen machine pumps air into her lungs around the clock.



Anthony Leoni knew they needed help.



"If you told us 10 years ago this is how your life is going to be, I would have said we're not capable. We don't have the training, ability, we don't have the energy, we don't have the stamina."



They found Bill Feeman of Westside Regional Center.



"When you walk into this home and you see Jessica, [you] just fall in love with her," Feeman says. "She is a sweet soul -- you see her, she's physically helpless, yet there's a light that shines out of her eyes, it takes you in.



"When you meet this family and you see how hard-working and involved they are, you just wanna do everything you can to help."  Watch the family's heartbreaking struggle »



Feeman worked to find in-home support in the form of nurse caregivers, therapists and medical supplies.



"This family also has all the normal responsibilities of raising a family. They have to pay their mortgage, they have to feed their family, they have to go to work. So when you have someone as medically involved as Jessica is, and you're talking about all that worriment and responsibility of your child being ill and on top of that you still have to ... bring home a paycheck every week in order to pay your bills, you need a lot of help.



"You have to be awake at night with Jessica. She cannot be left alone for even five minutes where someone is not awake and attentive to her needs. So you're looking at a family, who when I first met them a year ago had some help in the home but nowhere near enough and they were exhausted. They were trying to be caregivers, nurses, doctors, and then get up and go to work during the day and still support their family."



"We pieced all these programs together. We finally got everything in place where they can be parents again, which is a wonderful thing. And that's what scares me about these budget cuts ... it scares me a little bit that things might start moving backwards."



One of those caregivers is Carmen Bailey, a certified nurse assistant and home health aide with Caring Connection. She has been working with Jessica for more than two years.



"It's been an experience. I call her my angel. I bathe her, groom her, position her, massage her to make her comfortable."



Carmen may be affected by the budget cuts.



"I also have to live to keep on going. I know I will still be here and whatever I need to do extra I'm willing to do it for the family and Jessica."



Westside Regional Center is one of 21 state regional centers providing services literally from birth to death.
