Difficult emotions aren't moral failures. This realization led to a small shift that helped me stop the endless debate about whether or not I should be feeling something.
Because that's a place where I would often get stuck:
Should I be this frustrated? Should I still miss my old life? Shouldn't I be more grateful? And most of all, shouldn't I be happier than this?
The result was that I spent a lot of energy arguing with feelings that were already there. Eventually, I started looking at things differently. Instead of asking whether a feeling was justified, I started asking what it was trying to tell me.
Sometimes the answer was that I needed rest.
Sometimes it was that I'd neglected an important part of myself.
Sometimes it was simply that I was going through a difficult season.
Either way, the conversation became much more useful.
The feelings were still there. But I stopped treating them like evidences that something was wrong with me.
