Welcome Audrey! 
To make a topic (a thread) of your own, go back to the main list of threads (tap the blue circle at top left), then tap the “create a topic” button (the pencil-with-notepad icon at the top right). (See my screenshot below.) Then you give your thread a title and off you go!
Welcome to Talking Sober. You can do it. I personally found it was very helpful to connect with other people in recovery. I learned from them in podcasts and books, and I joined recovery groups, and I got a sponsor. (There’s a list of resources for this here: Resources for our recovery.) With the learning and daily simple effort, and with the daily accountability (I leave my sponsor a voicemail every day), I am gaining confidence and I am finding my sober feet.
