Those your doc picks: You don't make treatment decisions based on a simple online question. You need to have an ongoing therapeutic relationship with a doc who knows your full history, exam and lab findings. Treatment often requires a period of trial & error with various meds and dose levels. With fine tuning by an experienced doc you can get the most benefit.

Doctor will Rx: Depression and anxiety often respond to counseling and medications, especially those called SSRI's or SNRI's. See https://www.anxieties.com/156/selective-serotonin-reuptake-inhibitors-ssris#.XHSCV4hKg2w for a list of medications. Usually your doctor will start with one and then adjust the dose or change Rx if not effective. Individuals with bipolar disorder can become manic, so need diagnosis.
