As I said
earlier, I've been lower in energy since our holiday in mid-June - although the reduced energy is carrying on so long it may be simply because of winter, rather than the holiday. The last 2-3 weeks, though, I've been much less frustrated about it all - I've been mostly content, albeit punctuated with the odd patches of extreme panic!
One thing that has made a huge difference is a 'breath prayer' I've been praying. If I wake in the middle of the night and can't sleep, I start saying "You are the true vine, help me to rest in You." If I find myself fretting during the day, I do the same. God has used this to really transform my attitude :-)
