I am nervous about everything new!!! I am moving my kids to a new house, NERVES!! I am doing a new job this year too and managed to quit drinking while doing it. It is so normal, alcoholic or not. Just remember, take it one second at a time, one day at a time. You cannot project or predict tomorrow, so don't bother, you cannot change its outcome.
What you can control is TODAY. I always go back to the poem in AA Yesterday Tomorrow and Today
There are two days that you have no control over, yesterday and tomorrow.
Yesterday, with all its follies and pitfalls is gone. Tomorrow, the sun will rise, and that is all you can predict. That leaves today. Today is the only day you can control, and the only thing you need to worry about.
One foot in front of the other. That is how you make it through. Keep your sober friends tight, talk instead of drink. Get your feelings out there. There are many here to cheer and support.
You can do anything you want. Just remember that.
