@Roseshavethorns absolutely - my garden is so big and so daunting! I haven't even thought about the weeds.
At the moment I'm trying to keep on top of the grass. I'm also tackling the immense amount of brambles, mainly because the physical effort required is helping me sleep at night, and the repetition is quite numbing to my brain. I put a podcast on, and just slowly clip away. My aim is to get it all into a reasonable state so that I can sell the house in a couple of years time - it is too big and empty for me now, and will continue to be so.
The plans for vegetable plots etc are all going to one side - I will probably put as much as possible to lawn, just so that I can manage it all.
@Hisredipad it was a comment that you made on a previous post that has made me seek out grief counselling. I have no idea, of course, as to whether it will be effective or not, but I do have to rebuild a life for myself from the shattered remnants of my old one. Although goodness knows it feels like an impossible task most days.
