How did you change post breakup?

I'm (36F) not sure if my work has been affected and how I come across? I am not sure if I have become more direct and as much as I don't like using this cliche terminology "masculine". One client said I was quite direct yet I have other clients where relationships are so warm! I'm not sure if anything is coming through subconsciously. For context, I am. not crying like crazy and look like I am functioning fine but I really think there is more to my reaction. I can't put my finger on it. Anyone experienced a similar situation or finding it hard as you look all put together but internally something is wrong. I have cried on and off but even that not much.
