In the early days I just did what I had to, everything else I let slide.
Be kind to yourself, your body and mind need to recover and that will take time.
I went for walks, spent time with undemanding people, slept when I needed to and ate what I wanted. I put my sobriety first, had lots of help from SR, I would suggest you visit daily and ask for help if you need it.
Try anything and everything, AA, SR, don't rule anything out. Try not to let guilt, shame get a grip on you and take it a day at a time.
