Is this temporary?

This period of my life is definitely one of the hardest periods I’ve ever been in my life. My anxiety won’t let me see good things although I know they are there. I miss being stress free, I miss my old self, I miss my life when my perspective was different. Situations in life change you as a person and that definitely happened to me. I wish I was the kind of person who would go through difficult times and come out different but in a good way. Why do I feel that I came out different but in a bad way.
