I see you are doing so well under the circumstances. Some time ago I would feel kind of OK one moment and very low the next. I was an enormous roller coaster and I did not get why things were happening that way.
Today, I have those feelings, but they come more sporadic. I feel I have a little more control over my emotions. I also have more stuff going on in my life and they are not directly related to XH. It is one way, one road and it is building a life for ourselves that can make us feel better.
The YoYo of emotions, limbo, and all the pain that comes with it can take a toll on your, so be gentle to yourself and try to find joy on small things that comes across.
You are doing well, and in a much shorter time then I did. You are a smart woman and with your H or without him you will be OK.
