Mollie's Patellar Luxation Surgery

My name is Mollie and I am 14 years old. I have had joint issues on and off for years and mom took me to the vet and he said I have luxating Patella issues. What's that mom asked? That's where the knee joint basically pops in and out and causes me pain and to limp. I usually snap back after awhile but I still have been limping cause it hasn't snapped back into place. The vet says I need surgery to fix it :( can you please help me so I can feel better and not be in pain anymore? Mommy has to carry me to potty and to get up on the bed. Mom is on disability cause she has kidney issues so she can't afford it.  Can you please donate to help me ?  Any amount would be greatly appreciate. God bless you and thank you- Mollie and mommy!
