Yes, I was emotionally all over the place at one month. It was like that for a few more weeks (maybe 4 more). Looking back I'm amazed how anxious and out of sorts I was in comparison to how I feel now at about five months. I didn't realise at the time it was a kind of emotional rewiring. It should help immensely that you have the insight to realise what's going on.
And congratulations on one month!
