Mental health struggles take a toll on long marriage

DEAR ABBY: I have been married for 47 years. My wife has suffered from mental illness for more than half our marriage. Two years ago, she went off her medication, became manic for 10 months and was hospitalized four times. A few months later, it was discovered she had breast cancer. Fortunately, it was detected early. After surgery and radiation, she is cancer-free. I stuck with her through all that.
