I am already on Paxil 30mg daily for menopause however lately, I feel more depressed. do I need something else?

I have been on Paxil 30 mg once daily, for several years. I was first prescribed it by my dr. for anxiety and symptoms of peri-menopause. I am now 100% into menopause and now am feeling 'blue'. I find my level of concentration, my memory as well, my tolerance, has changed. Do I need hormone therapy, or another drug?
