mumofmonsters, re that verse - I always found a much more helpful one to be that one from Isaiah - something about even strong men grow tired and weary, and even young men stumble and fall, but those who trust the Lord will soar on wings like eagles, run and not grow weary, walk and not be faint.
It doesn't say 'those who trust in the Lord get to lie on comfy sofas and not have to walk anywhere' - we still have to walk the road, but we've got the resources to do it.
Am also reminded of that silly story about the woman stranded in her house during a flood who was convinced God would save her, and turned down offers of help from a neighbour in a rowing boat, the coastguards' launch and finally, as she was perched on the roof, from a helicopter, every time saying 'No, no, I'll be fine, I'm praying - God will help me'.
Eventually she's swept away and drowns, and when she gets to Heaven she stomps up to God and says 'Oi, I was stranded in that flood praying non-stop - why didn't you help me?'. God says 'FFS, I sent two boats and a helicopter, how much more did you want?'
Help comes from unexpected quarters - a bunch of random mums on t'internet might be the only angels you're going to get - make the most of them!
am thinking of you, just in case it'll help, and wishing you strength to get through whatever it is
