Hi Amy,
Opening up about you want to quit is a good start. It helps a bit if you got support back home as well. If I look back at my own recovery I can say it was difficult at the beginning. I had my ups and downs and worked hard to get where I am today. I learned a lot about myself.
I like myself a lot more then I did in my drinking days. Still growing mentally.
I never would wish for an addiction. But in a strange way it “gave” me a lot. Hope you understand what I try to say 
What has helped me a lot in my recovery was making a sober plan. I’ve shared it a few years ago and will share it with you. Maybe you see something you can use yourself too.
Don’t be a stranger and come here often, it really helps you to be here much. It helps you to stay focussed and you will learn a lot about how to become and stay sober.
See you around!
