I would recommend getting off the medication. Meds like that will cause health problems (liver damage) and make suicidal thoughts worse. You may want to try Anxius or Homeography.
From mentalhealth.com:
Use in emotional disorders:
Diazepam is not recommended in the treatment of psychotic or severely depressed patients. Precautions are indicated for severely depressed patients or those who show evidence of impending depression, particularly the recognition that suicidal tendencies may be present and protective measures may be necessary. Since excitement and other paradoxical reactions may result from the use of the drug in psychotic patients, it should not be used in ambulatory patients suspected of having psychotic tendencies.
