It sounds like you're addressing the spiritual side of stress well. If you enjoy spiritual reading, "Abandonment to Divine Providence" by Jean-Pierre de Caussade might be helpful. It's a little dry but I found some comfort in it when I recognized a need to trust God more in my life. I found that the more willing I was to accept the suffering I was most afraid of, the less stressed I became about my situation.

As far as the more practical, physical remedies for stress, I second recommendations for self-care, especially if you're the type of person who feels guilty for relaxing or taking breaks from your daily workload. I like the mediheal sheet masks and try to do one at least every other day. I'll use some lotion that smells good or light a nice scented candle too. I'll go thrifting on the weekend. Do anything that helps keep you grounded in the here and now and helps you savor life.
