give me a good wean off plan

i was thrown by a horse my foot got struck and while the horse was bucking i was being thrown up and down. the force was so hard that it ripped my pants and snapped the reins in half up by the bit. A few months later I was in serious car accident and now i have neropathy. Its not over, while walking my dogs that following winter i fell in -12degree weather with wind chill of -35, i fell had 2 spiral fractures to tibula and fibula.  Well I want to wean off.  My husband was not very supportive and asked me if with 12 inches of snow and ice if he sat a chair outside could i still walk 2 collies.  i had to chuckle at first i thought he was kidding, but he wasnt to my horror. I had to fly my mother around the world to take care of my kids because he wouldnt take off earlly and help. You should also know my best friend just died.  Just to survive i found there was nothing i could do but to function,was to take oxycodone.  Of course after one morning waking up with  pins and needles and a feeling that my hand was going to explode and pain going down my leg i was already depressed but lost most of my feeling in my right arm for about 4 hours with the exception of the feeling of my handexploding as a finally.  Well Im now going threw a divorce, and again feel alone with no help.  i have by myself come from 2- 30s to 2- 15, to 2-10's almost instead of every 4 hours im also down to every 6 hours or 4x a day. depending on the day.  i horribly upset i lasted all my life not drinking, smoking, or any kind of drug and here i am. I couldnt sleep so my dr put me on xanax which im now told is addicting and am weaning off that. So then he gave me gabapentin and this i hate but i will take 1/4 every now and then at night s i can sleep.  Can anyone help give me a good wean off plan that i can do quickly as possible and still be healthy. Sorry if messy trying to type quickly so that knowone sees.  I know I will have this for the rest of my life but would like to see what real pain level is after weaning off.
