It’s great that you have such a supportive network in your life. The importance of that cannot be underestimated.
What I meant about making your sobriety the top priority is that for me, I have to balance the things I do each day against the standard of “Is this good for my sobriety or a threat to my sobriety?” I’ve been sober a long time, and I’ve worked with lots of other men who were getting sober. What I’ve seen is that the ones who failed, who returned to drinking and drugs when they did not want to, were tripped up by one of two causes, generally. Either they started working massive amounts of hours to get as much money as possible, or they became entangled with a romantic/sexual partner and replayed old past failure patterns in the relationship.
Both causes of relapse come back to a common root - staying sober became less important than something else. And the way that priority shifts starts with little decisions, like “If I miss this party, people will talk about me” or “If I don’t go, I will never have fun again” or “I have to pay this bill in full, it’s too embarrassing to make payment arrangements” or “If I am alone for a day or a week, I will go crazy”. And the deeper common attitude was indulging a fantasy that (switching to my voice now, in the first person) I am not really an alcoholic, that people cannot know, or if they do know then they cannot know just how terrible it really is. My attitude that I could handle it, that it wasn’t that bad, that I had to hide and shun that most critical fact, that almost killed me.
I had to acknowledge my alcoholism by growing my sobriety. I came to regard my alcoholism not as the beast that controlled me, the monkey on my back that I could not shake, but instead as a frightened crying child who would lash out and attack when any attempt to console him was made. And the way to deal with a child like that is to keep offering love and acceptance, until the lashing out stops and the child accepts the hug and the safety.
My drinking had become pretty much a full time occupation. Every single day, I had to recover from the previous bout, plan how I was going to get more that day, plan how I would make time and space that day to drink, plan how I was going to explain away or deny or ignore the consequences that were mounting up and would not stop. So my sobriety too required that same level of effort. What was I going to do that day to stay sober? Would I follow my plan, starting with a sober morning routine? How was I going to replace my active denial of the depth of the problem with active recovery?
In AA, I heard the somewhat glib statement that “Whatever you put in front of your sobriety, you will lose”. I needed more explanation than that, and for me it came down to how I introduced myself in AA meetings. I switched from the perfunctory “Dan, alcoholic” response during group introductions, to “I am an alcoholic. My name is Dan”. That focused the issue for me - at the core of my behavior is the fact that I am an alcoholic. Drunk or sober, I am an alcoholic. If I try to be something else first, then my alcoholism will recur. It must be treated or it will demand indulgence. From there, I added two movie quotes to correct my attitude. These remind me that I get no time off for good behavior when it comes to dealing with my problem. My intentions do not matter, only my actions and the impact those have on the people in my life are the proper measures of my commitment to my recovery.
Yoda - Do or do not. There is no try.
Any Dusfresne (Shawshank Redemption) - It comes down to a simple choice, really. Get busy living or get busy dying.
So the issue of deciding whether to go to a party in early sobriety, or at any time to try something as a test of one’s willpower or to minimize the vicious strength of addiction and how the smallest stimulus can re-ignite it, has more depth and meaning than is at first apparent. The balance of being sober with living in a world full of drinkers and booze has to be acknowledged as real work, requiring real effort. Occasional, or time limited, withdrawal from alcohol circumstances is an important way to re-align my attitude toward my sobriety and my reliance on what proves to be fleeting approval from other people.
If you’ve reached the end of this treatise, I am grateful you have stuck with it. I welcome your feedback.
Blessings on your house 
as you continue your sober journey.
