Welcome to the community Kayla
Great job on your 3 days of sobriety. Do check out the links that @SassyRocks provided. Also - are you planning to go to any meetings (in person or ones online)? The meetings can be very helpful and also a great means in finding a sponsor that you can talk to in real life.
Being a part of this community has been a life savor for me. I can’t get enough time here. I feel that whenever I am at a low point - i just log on read through the many threads. It helps more than I can explain to ready the posts and also be of help to others that are struggling.
I would also suggest that at the beginning you may think about changing up your daily routine (especially since the weekend is coming up and this is where most are super vulnerable). Plan activities or events that you can do sober and keep you occupied - pick up hobbies or start new ones.
Feel free to ask questions. I find the Checking in daily to maintain focus #55 really helps keep me accountable.
Best of luck on your journey! Hope to see you around.
