Ashli, it's good that you found this forum. So many people have gone through what you are, and there's lots of help and tips here. I have found it to be a lifeline. It's so hard in the first weeks of trying to quit.
Just don't beat yourself up about it; just start over, like from right now.
I've noticed that alcohol did make me feel more depressed, and I had a lot of weird anxiety, that went away after I quit, I didn't even know that was related. Good for you for seriously wanting to quit. You're still young, don't let 20 or 30 years go by like I did....
