osteo radio necrosis

I have osteo radio necrosis that appeared 1.5 years following radiotherapy to the left side of my neck for left tonsil cancer with lymph node involvement. Parts of my jaw bone are exposed as have died and the skin in my mouth is receeding. This means the dead bone is infected. So far I have had 4 teeth removed and part of the jawbone to try to heal it and now I have other areas open up and the operaed area is not healing due to poor blood supply to the area which caused it in the first place.
It is very painfull and frightening and I dont know of anyone who has this. Its getting worse each day and I fear I will have to have the whole jaw removed if they cant do anything for it. I would rather die than live with that especially here in Ireland where top quality surgeons and plastic surgeons are thin on the ground. Ive been struggling with this for 2 years now and am attending the dental hospital almost weekly at great financial cost as it is not covered by my health insurance or stamps. Im working to pay the dentists looking after me and in debt over it also and really cant cope any more.Can anyone offer me any help or advice, It is quite a rare side effect and Im not overly confident I am being treated properly for this. Im In Dublin Ireland and from my research we are way behind other countries medically.
