reintegration into the work force

i have successfully survived my cancer experience twelve years; however, i have had difficulty reintegrating back into society. i believe that our society is lagging with respect in knowing how to deal with cancer survivors and their related side effects. my long term side effects include chronic lymphedemia and shingles. these prevent me from working full time. i am a very qualified engineer, but can't deal with the related stress. it activates my side effects. is there any support efforts for helping surivors reintegrate into the work force? grants available for long term survivors? reeducation?
