That's great to hear. Yes, kind to yourself is so important. You'll get there and it won't be as hard as you think it will. This is going to be a teeny bit of a roller coaster, feelings change from hour to hour or day to day, that's why it's so important to have that self care and kindness, so you can always be on the best possible footing. If you allow yourself to get over stressed, over tired, hungry, well you know the result, which brings to mind!
H.A.L.T.
When things start to roller coaster and are getting on top of you, it can help to stop for a minute and ask, am I hungry, angry, lonely, or tired? These things can be addressed as soon as possible and will help you stay on a more even keel.
You are sounding strong. You are you know, what you have just written, all you have been through and managed to keep on keeping on. As dandylion often says (paraphrasing), if you have the strength to live with an alcoholic you can absolutely do this.
