Welcome to the community, Kita! I get that things feel pretty hard right now, but don’t worry about the first week of withdrawals. Just decide to be sober right now, here for this moment, one minute at time. One day at a time.
Lots of people use the Checking in Daily thread. It’s a great way to interact with others here, and also helps build some accountability. 
Stick around, read how others have conquered the first few days and longer. There’s a lot of motivation to be found on these threads! And lots of wisdom that comes from experience. We never have to have another Day 1.
