Emotional

Hi everyone
I recently had surgery for galbladder removal that was kind of unexpected. I'm not sure if it's because I didn't really have time to feel my emotions but, I have been feeling sad 😔, scared and like I want to cry from time to time . I'm on day 6 , and it usually tends to happen more at night but did anyone else experience similar emotions ? I am okay but from time to time this feeling will pop up.
