To me, there are two sides to this...

The first would be stop going because it's very expensive and maybe you need some time to decide that you want to get better.

The other side - the one I tend to go with in your situation - is keep going. It took me almost 3 full years to start getting any benefit from therapy. While this isn't the norm, sometimes it just takes time to be ready to really do work. For me, I was at a place where I just wasn't ready to do work.. but I knew I needed someone. It's ok to just need someone even though you're not making any measurable progress because you are still absorbing and becoming more self-aware. Judging by my experiences (and yes, I'm only one person) I'd say that eventually something is going to change and you're going to want to make progress.

Honestly, a good starting point is to have this conversation with your T.
