Exhausted

I am so physically and mentally exhausted at the moment.
I can't remember the last time i got a good nights sleep, or even a 'meh' nights sleep. It's been well over a fortnight.
As exhausted as i am, my body won't allow me to sleep. It likes to torture me. My mum looks genuinly worried about how shattered and run down i look most of the time because i just can't sleep.
I just need a good nights sleep, or two, to at least recover a tiny bit. I cannot deal with this.

And i'm mentally exhausted with everything.
I'm really glad that i have somewhere to stay so i can actually move to Lincoln now but it's really not that simple. First i have to sort out allll of my bank, doctors, dentist, ect, move it all to Lincoln. Get a tennancy license with who i'm staying with. Get the money starting to go to them.
Then i have to obviously pack up all my things, all my clothes, most of my personal belongings, and somehow find a way down there with all that since we can't drive there as my mum can't drive and my dad has fucked off forever now (which is good except it'd have been OK for just a bit longer if he could have drove us ok)
Then i have to settle in and unpack and get everything just right and spend a week or something getting them to trust me and getting myself comfortable in someone elses home.

Also i'm really upset at what i got told today.
Apparently my nana is considering not having any treatment for her cancer because it's not cureable, even though it could reduce the size and prolong her life.
But she doesn't want to get really sick off of chemotherapy.
I know i'd most probably do exactly the same in her position but i can't even think of how much it'll damage my mum. She'll have no one.
She has no friends, and really only talks to me and her mum up here.
With me in Lincoln and my nana potentionally dying, she'll be alone.
I know she'll probably move down here if she does die so she can be closer to me, but i will feel so guilty.
Why did i have to time things so wrong?
