Life feels very hard today

[Needafriend2019]

I'm struggling today, I was meant to be meeting my best friend for tea today she lives 25 miles away so were going to meet in the middle but had to cancel due to the snow.
I'm really unhappy in my marriage and I've been holding it all together knowing I could have a good chat with her tonight. Oh has come home from work there's been cross words at the dinner table and ds was really upset, I'm fed up of walking on egg shells and I'm fed up of every mealtime ending on a sour note, I want to leave oh (well I want him to move out) he doesn't know yet and I think it could be months until I'm in a position to tell him.

Work has been hard today I just feel like I'm failing at everything, there is a job online I'm thinking of applying for closing date is Fri am but I'm so down and negative today don't think I can write a good application.

I feel overwhelmed with life and I don't know how to get out of this mindset
