I think being aware of the block is the first step. We can't work on things if we're not even aware of them.

T told me once earlier in therapy that he could see this moment sometimes where I was about to share something or feel something and then I would hesitate and totally change the subject. He asked if I could notice when I did it, and I definitely could. And then he asked me if the next time it happened, I could stay with the thought/feeling for just a minute. So, I tried it, and over time, I started being able to stay with the hard stuff even longer. So I wonder if you could stay with the thought/feeling for just a moment? I kind of think of it like working out...it's really hard to do it for even a short time at first, but over time, it gets easier and we can work out for longer and longer periods of time.
