I always suggest people to accept where they are with no judgment. If you feel unsafe to feel "safe", that's okay. I'd suggest to trust that you are exactly where you need to be in your healing process and not to fight what IS. Whatever you are feeling is the reality that needs to be accepted before you move elsewhere. We feel whatever we feel for a reason, so there is nothing wrong with how you are feeling at the moment. I hope your therapist has enough wisdom to be present with your current state of mind. If he manages to do that, then, after some time, you will naturally move into a different state effortlessly. You don't need to do anything for that to happen. It'll happen in its own time when you are ready to let it happen.
