My worries today

Last few days I've been moody as hell and so tired, like deep into my muscles, barely function tired. I feel guilty snapping when I shouldn't, but I cant stop.
It's my birthday next Tuesday and J's birthday next Thursday. We are going to my mums for tea. Mum said about maybe making potato bake. J doesn't really like it. I told mum then she gets cranky about it. Then I feel bad. And then I feel upset too cos it's our birthday.
This is why I don't want to have an actual wedding anymore. I want to get married but I don't want a wedding. Becasue this is how I'll feel.
My 18th was ruined, my engagement was ruined and I know my wedding will be too. So I gave up on something I was dreaming about my whole life.
My sister wants to move out. And I dobn't blame her. But she doesn't know how to tell mum and I don't either. And it's not really my thing. This is hers. I had to do it on my own...
I feel like an emtional and physical wreck and I just want to be left alone. I can not stop panicking and feeling worried and guilty. Its not fair that I feel so crappy. Im not even 24 yet.
