Suggest Treatment For Migraine And Depression

I am ready to commit suicide. Have had headaches, pressure pain, and clicking noises that my doctors brush aside with how do you make that noise . They keep giving me pain killers and diagnosed me with migraines, yet migraine medicine does nothing to help. Plus, the pressure, pain and the noises are unbearable. Have had tons of MRI s and CT Scans, there is a polyp on my right side, and one has already been removed from my left side. Doctors do not want to follow through, they say that is not causing my problems. I am in so much pain, discomfort and also upset, not to forget depressed. Help.
