I know nothing of GOD's timing. It doesn't concern me anymore. But I know that the way we look at stress can FREAKING KILL you! Scientifically, it's not the stress, but the attitude toward it. So embrace it. It's gonna happen. Stoicism can save your life.
...even when we're being bombarded by thoughts that we don't want to keep popping into our minds: we can offer up those thoughts to God in prayer and ask Him to help us identify what's really bothering us, and what we really desire, that we may be seeking in the wrong way.
