I have used several sessions of hypnotherapy for grief issues; I found them very helpful
I also use meditation and diaphramatic breathing to lower anxiety about chronic pain. It is surprisingly effective. Recovering from heavy-duty orthopedic surgery five months ago, I have used these techniques daily. I had forgotter what a powerful tool they are.
I keep a copy of Full Catastrophe LIving: Using the Wisdom of Your Body and Mind to Face Stress, Pain, and Illness by Jon Kabat-Zinn, around for reference. You can pick up a cheap used copy at Amazon.
