That sounds like a challenging interaction at 8 days sober, which you handled quite well. 
Congrats on that and on your 8 days!!
My recovery hasn’t included a sponsor (I am not in AA), and if you are looking for additional suggestions and resources to add to your sobriety toolbox and AA, maybe some of what has helped me might help you.
My recovery plan over the years has included…
Being a very active member of Talking Sober. I have consistently been on this forum for years of sobriety. I strongly believe that sober community support and connection are vital to healing ourselves and sustaining sobriety and recovery and building a healthy and healing new life.
Over the years I was also active in these online communities…
Reddit r/stopdrinking
Women for Sobriety (WFS)
Soberistas
She Recovers
Additionally, my recovery has included…
Putting myself to bed early and often in the early days.
Yin yoga, bicycle riding, HIIT fitness classes, hatha yoga, walking, yoga nidra, running, hiking
Meditation and sleep meditations
Mindfulness
Eating a lot of sweets and then after a year and a half, quitting sugar and processed carbs
No wine in house
Journaling
Hot epsom baths or soaking in the hot tub (especially helpful when anxious)
Eating clean / drinking a LOT of LaCroix, now I drink tap water
Reading and rereading a LOT of sober memoirs/novels …see my list here…
Keeping a list of how I want to live my life/what sobriety offers…I keep it on my phone and when I start thinking, hey, maybe just one glass of wine, I read my list and remember how desperate and unhappy drinking made me. Here is some of that list…
