Don’t be too hard on yourself. Big social events are really tough, especially early in sobriety. When I quit alcohol in December, Christmas and New Years was coming up and I really wasn’t sure I could make it through sober. I chose to avoid big drinking events for a while and do something rewarding in a sober environment instead. For me that was volunteer work and teaching kids.
Giving myself the time to settle in my sobriety for a few months was really worth it. I learned, that I can have a lot of fun without alcohol and it really isn’t needed, to make great memories. I found new people, who don’t need to drink and I stick with them, when it comes to festivals, concerts or any other big social event. Pick yourself up and try again with a better strategy for next time. Best to you - putting up a link on how others have handled this
