@BoneTiredandWired welcome. Of course you can join in, and you can stop, however impossible that may seem. It comes down to working out why you drink - there are as many reasons as there are people on this thread, and you will have something in common with all of us, but there will be other areas where you are completely different. Think of it like a Venn Diagram. We all overlap in that we drank too much and decided to stop, some of us are in the 'unhappy childhood segment' and in the 'addictive personality' one, and others in the 'physically dependent' one, and so on. It would be so much easier if one size fit all, but it doesn't.
If you get withdrawal symptoms (beyond feeling a bit weepy and fluey) when you don't have a drink for a couple of days you might be physically addicted and should speak to your GP. It is dangerous to stop suddenly, as I'm sure you know. If you aren't physically addicted, you might like to replace your drink of choice with an AF alternative, so you go through the motions and rituals, but without the booze. That was really helpful for me, but others find it triggering. Whatever you do, get some Vitamin B1 (thiamine) and take a high dose (you will excrete what you don't need, so you won't overdose). That can prevent you getting brain damage - sorry to alarm you, but there is a slight risk of that, but if you take the B1 (it's fine in a VitB complex) you will prevent it.
I found other rituals useful, such as scented baths and hypnosis tracks through sleep headphones. Not everyone would like those, but for me it took away the fear of lying in bed unable to sleep, and I found it relaxing, whether or not the hypnosis worked. The headphones are cheap on Amazon, and hypnosis is widely available. Craig Beck is as good as any to start with.
Work out your danger zones and what to do in them. I carried on going out, which included licensed premises, but switched from wine to lime and soda or AF drinks. After a while that stopped - partly as I changed my friends, and partly as it just lost its appeal, but it stopped me feeling deprived when I was still missing the booze.
If you are worried about physical damage (oddly, a lot of drinkers have health anxiety, yet continue to put ourselves at risk) wait three months or so before getting LFTs done? That way you will be measured when there is no alcohol in your blood, and the repairs will be well under way, so there is far less chance of getting anything harmful on your records that might come back and bite you.
And keep posting. Knowing that people are here for you, and promising yourself that being part of something depends on your sobriety is a real motivator. I've been stopped for 7 years now, and posted elsewhere when I stopped, but it was the same principle.
Do it for your children, if not for yourself. If they don't grow up with a drunk for a mother they won't thank you for it - motherhood is a fairly thankless task 😂 - but they won't blame you, which is more of a blessing than you can know.
