Welcome Nikki 
it’s shocking to realize these things but it’s a wake up call and that is a good thing.
You’re right that you can’t drink again - or more specifically: the consequences of drinking again are bad, so bad that you choose not to drink again. You choose to be healthy and grounded, because that is what keeps you alive, for the people you love (which includes yourself).
24 hours at a time is all any of us have. It’s all any human has - so really, being sober, you’re just learning how to be present and “ride the wave” of life like any other human needs to, without the numbness of booze.
The good news is this is a new chapter of learning and growth! You are going to come out of this stronger.
Hang around here on Talking Sober and see what TS has to offer. There’s so many good threads!
Maybe check out a sober group too. For me it made a huge difference and I have close friends now that I made in that group, when I started my journey. Sobriety groups are a significant help for many people getting healthy and grounded, because it’s a space we can learn new mindsets and new ways of living in the world, without running to booze for escape. There’s so many good options:
This thread has other sobriety groups and also lots of informative podcasts - for learning about this new journey 
This is a big choice but it is your choice and it is a necessary choice. Yes you are changing and there is something you need to cut out of your life, but the positives are so, so much better than what you give up. One day at a time
