What your T is saying really rings true to me. If things weren't painful or difficult, we wouldn't bury them, so when we try to go towards them, it often starts to feel more difficult or like we're "emotionally stuck." BUT, and this is a biggy, the fact that you're aware of how you're feeling, talking about it with your T and trying to figure out what those feelings mean are a sign that you're NOT stuck. You're moving towards the deeper issues. But it's a lot of work and can sometimes go painfully slow.
I know sometimes when I'm really struggling for answers, it helps to give myself permission to NOT have the answers, to just say whatever I'm feeling or thinking without editing or judging it, and let my T help me figure out what is going on. You don't have to figure it out all on your own.
