Briar, you did it. Yes, it's hard. Yes, you can do it. No, it is NOT impossible, even when you feel it is. Rough patches happen. Take a deep breath. Cry if you need to. I did, a few times. Sat there in my car and crying to myself that I couldn't do it. That I'd never be able to do it. It physically hurt sometimes but I made it through. It stinks in the beginning but it is worth it. Keep going. I was going to say "fight it" but fighting is exhausting. Surf it instead. Surf it out. I'm glad you came here.
But what fini said is true. What support do you have to help before it gets this hard? I started reaching out all the time, whether it was to simply say hi how was your day or an "I'm not drinking today, how are you doing?" It made things a lot easier. So I have a bunch of people I can talk to, vent to, ask questions of. An army of sober supporters in addition to coming here. You can do it. Hugs to you.
