Welcome back Five! I found that staying focused on the present really helped me with sobriety and life! You can’t change your past, only learn from it, and worrying about what might happen in the future only ruins your present moment.
I found reading and posting here often was crucial to my early sobriety. I am getting close to the five year mark, and reading and posting here is still a big part of my recovery.
You should join the October 2020 class, and also the 24 Hour Recovery Thread. Both are great supports!
