Hello metmom, I can tell you what works best for me.
I focus on myself when it comes to activities pertaining to this life. Such as keeping as fit physically as I have strength. Exercise is good for so many ailments and especially good for those who have PD. I need mental stimulation including challenges. I find working on genealogy fills that bill. When I engage in social activities, I choose carefully who I spend my time with, some friends give to me, some I give myself to.
I focus on God when it comes to spiritual activities. I am more aware now of how much closer I am to heaven. I want to know as much as I can about the God I will spend eternity with. I only listen to teachers that I trust will broaden that knowledge. I read authors that are biblically sound. RC, of course, MacArthur, and currently I am reading Rejoicing in Christ by Michael Reeves. The focus is God, not me.
Some days, I fail to endure quietly. I cry out to God for sleep! Tomorrow is a new day.
Works for me.
I do the best I can for the stuff that’s my responsibility (eating well and exercising and getting enough sleep) and the rest is God’s (the healing part)
