Hi Mama, "New normal" is something I learned in my own cancer journey (18 years ago!). Things change - but it's ok. It's not what we expected, but it's ok - different, that's all. My boss always says "All change is good change" - well, I can't really agree with her there - but I think she means that with changes come opportunities.
Good for you for detaching. It brings peace. Yes, there's still anger, and resentment, and sadness, but I have found that as I start to detach, I can compartmentalize those feelings a little more. H feels remote and distant and almost not like a real person any more. It's weird. But I feel better.
When H moved out and then my kids went off to college, it was so jarring. I hadn't lived on my own since 1998! But now, I'm used to it! And I like it. It's my new normal. I think every day is going to get easier for you as you adjust to your new normal. And it's really healthy for you to understand and embrace that.
Wishing you continued peace and strength through the holidays.
