Severe insomnia after chemo treatment for 32 years

Options

Has anyone else had this, its about drove me crazy,and doctors just say its depression but after 15 different anti depressant mess I still have not been able to sleep more than 1 to 2 hours a night if I sleep at all, keep telling doctors I think the chemo damaged my area of the brain controlling sleep but they still won't help. They have never tried Valium or Xanax on me , those may not work either but I wish they would at least try it. They tried ambien on me could take 2 at a time and not fall asleep. I lost my job and insurance while taking chemo so I was unable to go for follow up with my cancer doctor
