I don't know if you mean to move forward in life or if you have some trouble doing things you have on your to do list.

I am older than you (and in that way have had a longer time to grow in my grown up years) and I can remember from my student therapy that there was topics I was afraid to touch. Now, many years later I am able to look at all of it ("This is my life and so it was. I can accept that. I can accept myself").

I always had a strong "push-factor" when it came to growing, and so it happened with the topics I once was afraid to face as well.

Take it to your therapist and be open to suggestions ... , and let it take the time it takes.

If your topic was to avoid doing things on your to do list, that is what happens to me. It has become worse after the corona lock down. I am sitting there and just let my thoughts pass by. I am working on it. I bought a book at Amazon (kindle) yesterday about overthinking. I don't know if it is that it is about or has more to do with being afraid to move (in the here and now). I do remember times in my childhood where I had to hide and be silent as a mouse. Anyway, if it is this or that explanation, the book (have only read one chapter) reminded me about that "things" are intermingled (hormones, memory-traces, early childhood effects , effects in the real time, social bounds and more). To remember about all this "intermingledness" helped me to relax a bit and to believe that this problem can be overcome as well with time.

I wish you well with your problem. Whatever it is, it has it's natural causes!

(Me too get the feeling of being hopeless and of no worth when the "no-doing" happens to me. That is why I want to do something about it and try to be kind to myself in the process).
