I'd add to what Sunny said: sometimes we have to work through the same stage multiple times before it really takes hold. It is just where you are and what you need to be going through right now in a way. I suspect it is also different this time through. You aren't really back to square one. You are aware of what you are going through this time. So now you get to watch yourself struggle and adjust. The first time, you couldn't really see it for what it was. Now you get to more fully experience it. You'll have different insights this time through, and you'll probably be able to embrace it this time for what it is. Then, maybe you can let go of some little piece that you're stuck on.
So, don't be hard on yourself, recognize the ways in which it may seem like it was before but I bet you can see and therefore appreciate some growth and development if you look for it.
