Hello and welcome to SR! I am so glad you saw the doctor you did at the ER. The first few days are the hardest, and you are past that now, so staying sober means you’ll never have to do that part again. This website is a wonderful support, you should consider joining one of the monthly classes, all you need to do is post in that thread to join, June of 2021 is currently open, and July of 2021 will start soon. The nice thing about the classes is that you will meet others at the same point in recovery as you, and will also have the support of people with more sobriety under their belt, because they pop in to lend an ear, and offer suggestions.
Getting face to face help will also be good. IOP would be great for a bit, you will get lots of support and strategies, and that may be what you need for this next part of your recovery.
Reading and posting here daily helped me stay sober, and I’ve met wonderful people as well!
