AwkwardKitty it must be after midnight in the UK, right? It is 7:30 p.m. here on the east coast USA.
I've got a hundred and one questions, I am quickly realizing, but I'll just post a few for you to think about and answer here if you wish, or post anything else you wish, but please do post again soon.
You are sure about keeping sober tonight, right? Do you have alcohol in the house?
What's your plan for the night? Is it bedtime?
You say two of you are working at home. Is the other person aware of your wobble? Is s/he a drinker?
Get through tonight. Then get through tomorrow morning, then afternoon and night, then the next day. That's how this works, right?
