Mental experiences of self

Hi everyone,

Since losing and birthing my firstborn end of 2023, I've experienced some changes in myself but it's been really hard to pinpoint exactly what. I know I'm still relatively new on this grief journey, but it's been bothering me so much that at times I feel like there is a version of me within myself I don't recognize?
I fee like it doesn't matter if the cause is grief, aging, postpartum hormone - I just need to clarify exactly what's different. But it's hard.

For example...

• I now often forget to take my keys leaving home
• I keep worrying about my work when there's nothing to worry about
• I can't write things succinctly and always seem to add more details - can't gauge what's necessary and what's not
• Sometimes I come out of a room and have no idea where I'm going
• I don't know if I'm sad or I'm happy or I'm somewhere in between

I know pregnancy hormones literally change our brain. It terrifies me that I am a new person yet I have no idea what's changed now. I talk and act in a way I don't quite recognize at times (like - what am I really trying to ask this person? Or to get from this conversation? What's my point here? Do I EVEN have a point?)

Anyway, just curious and want to know what other people's experiences are, and maybe if their reflections have gotten them somewhere.
