We have ALL been there.
But seriously - take a look at where you are now: Upstairs in bed hiding from your husband and children because of the state you are in. Feeling like death. The shame.
Does it look like something you would miss?
Just like MrsS I hope I don't sound patronising. God knows, I was a shocking drinker and totally know where you are coming from so do hope I don't sound smug on any level.
But if you are 'one of us', I suspect the reality is that you can't have a nice, social drink. I miss that - but the ability to 'have a laugh' in a half-way ok fashion left me years ago. I miss what I was able to be like a decade or more ago. The reality is - that isn't an option for me anymore. If I drink, it all goes pear-shaped.
So - assuming you are the same - you have nothing to 'miss'. Also, totally agree with MrS, if you can - try not to project and look into the future. Will my life be boring and empty without booze etc. Just try not to drink one day at a time. SO much easier to manage. I still don't tell myself I will never drink again and it's been over 2 years.
Hen dos are tricky. I haven't had to go on one since I got sober (am too old!!), but if you have one coming up I'd seriously think about making some excuse and not going. Holidays without booze are WONDERFUL. You actually notice and enjoy where you are, don't feel like death, enjoy the company of DCs rather than finding them irritants that get in the way of your drinking. Read books, enjoy local food/sights. Etc.
I promise. it's about a billion times better than how you are feeling now.
One step at a time. We are all 100% behind you. Be kind to yourself xx
