You might want to mention your situation to your primary care doctor. Newer antidepressants are better than those which were available years back and they do usually work, in my job as a medical transcriber, I frequently hear of benefits from these drugs. The doctor can probably help you with meds or point you to a counselor. Feelings of being ashamed of this common mental difficulty are normal for men and also for women but do talk to a professional about your problem. My husband of 40 years has lung cancer, advanced, has been through radiation and chemotherapy and now has decided to just take some herbs and enjoy as much as possible whatever time he has left. He has good days and some that are not. If you believe in prayer, that is a plus. God can do what man and medicine cannot do.
