I'm confused lately I don't know how I feel there's times when I'm so happy but there's times when I just want to curl up in a ball and cry I'm confused

I'm confused and I don't want that confusion to force me to shut the world out force me to step back when I took so many steps forward I don't know how to not be confused when I don't know why I am is it because my life is changing and it's no longer familiar to me I made the decision to get a new job and I'm happy I got the job I think I honestly don't know how I feel I'm so confused and it's frustrating and confusing and I don't know the answer I'm just I'm confused
