Help me walk again!!!!!

My name is Katie I am 32 years old married to my wonderful husband Paris for 10 years and a mother to 3 great kids Ethan 14, Aubree 12 and Owen 10 and I don't know where to start... I have CRPS ive had it for 2 years now, ok try to stay with me here it gets,confusing
I have severe Crohn's disease which is an inflammatory bowel disease and have had 20+ abdominal surgeries so when in feb of 2015 i had to have another surgery to repair a parastomal hernia and remove my uterus due to complications from Crohn's I thought it would be like all the others. On Feb 19, 2015 i had surgery... Now i dont remember any of this but later that day i woke up and told my sister i couldn't feel my legs but they hurt so badly, well then i got deathly ill and was rushed to the OR for surgery to repair a blockage they caused, and within 72 hours i had a total of 5 surgeries because when they went to fix the blockage they punctured my intestine i was so bad i was also in a coma for 14 days on life support i woke up almost three months later! When i did my legs hurt so bad i couldn't stand it ! But i couldnt move them or feel them except a weird numb foot fall asleep feeling but a billion times worse! So after being discharged and sent to a rehab i was told the first surgery which was done with a robotic machine destroyed my peripheral nerves to my legs, i am now wheelchair bound and have not had one sinlge day without pain! I haven't been able to walk since .
I was told by a friend about Dr. Tim Tollestrup he is one if 4 surgeons in the nation that preforms this miraculous surgery to decompress the nerves which are preventing me from being able to walk I will need 2 separate surgeries the first is August 29th and the second will be 6-8 weeks later, during the surgery I will have four incisions one in my buttock, thigh, behind my knee and foot. I have insurance but the copay for each surgery is $875 that we just don't have so please any small amount will get me closer to being able to walk again!
