Welcome to SR SickInLove. I see you have a similar thread started over in Newcomers so I'll just add that you are more than welcome here and we hope you decide to stay around for the support and understanding you'll find here.
We can definitely relate, anxiety and helplessness are things almost all of us felt towards the end of our drinking. I personally suffer from health anxiety ( diagnosed ) so I totally get it. Drinking definitely won't help, in fact it will make the anxiety worse eventually.
Most times our spouses/SO's don't understand addiction so to them, a suggestion of "just stop drinking" actuallly makes sense to them. They see that drinking is the cause of your problems, so logically quitting should help, right? And it will...but there is more to it than that.
I would suggest seeing a doctor again if you think that you have medical issues. Even if you don't, it will give you the peace of mind, and you can also discuss your drinking with them. They can help too.
