Hi Beep, sorry to hear about your struggles 
It’s hard for us as we build up our sober life, from the ground up 
Have you tried an online meeting? There are lots - and because they’re all over the world, there’s usually one starting whenever you want one:

Be gentle with yourself. One year is an accomplishment but it’s still early days in terms of your sober life (compared to all the years before this one ). We addicts learn a lot about our self-concept, our sense of who we are and what we want and how we do things in the world, in recovery. We’re exploring how we operate in the world sober. It’s like learning to play the piano, or learning to cook. It takes time, and it’s about persistence.
Gaining a bit of weight isn’t the end of the world. I’m not saying that to be dismissive, I just mean, in the big picture, youve already achieved so much and you’re still walking forward every day. That’s something you can celebrate. You can explore diet and exercise options if you think they will help you live your best life. Just remember you’re already good enough, as you are.
Take care and remember: you’re a good person who deserves a safe, sober life where you can be your full self.
