Welcome, jrv3! It sounds like you have several challenges in your life that you have made the conscious decision to take head on in order to make you healthy. It's a big decision, but an exciting one, and one that many people around here will say is one 'a year from now you will be glad you chose today.'
Hopefully through this website, other sources, and your own determination you can start to use food as a different kind of 'medication' that heals and nourish you, inside and out. You'll start to see your body as something you want to take care of by providing it with good nutrients. It's a transition that comes slowly but it will come.
I'm not married so I wouldn't be the best person to offer specific advice on your relationship with your husband, but wanted to reach out to say welcome, and best of luck on your journey! You have a lot of people already rooting for you on this board
