I was in talk therapy for 4 years and evolved from being completely sick and unable to work or develop intimate relationships to being now fully employed, in an intimate relationship and committed to self-actualization. I agree with many tips given in this discussion:
You should have an open mind
Honesty and not projecting
Work on being vulnerable
Uncensored relationship with the therapist
Meditation. If you haven't already, start meditating and keep meditating for the rest of your life. Meditation great tool for learning to observe yourself, among other things.
Awareness of the body and emotions (body awareness was the one thing lacking in my therapy and my results would have been much better with it!)
In addition:
Uncensored relationship with your therapist requires safety. When choosing a therapist, be as picky as you are. You need someone who you can potentially open up to about everything. Political correctness is not something one should worry about. For example, I needed a female therapist for some reason and respected this need. If you feel like some therapist really is not good for you, don't be polite and stick with them - there are plenty of therapists out there.
Talk about the things you don't want to talk about. Unwillingness to discuss a topic is an indicator that this is exactly what you should talk about and great growth can result. You can start by talking about how something is difficult for you to bring up. Like Erlend K said, explore the unwillingness to talk about the topic
Accept that you will not be ready and 100% perfect after therapy. The greatest asset you can get from therapy is the routine of observing yourself and working on your issues. This continues for the rest of one's life.
I do agree with this to some degree. However, in order to let trauma resurface, a feeling of safety is needed and this can be built in therapy or other people can help provide it. When I started therapy, I had no idea what safety even was and my trauma became accessible only after I found that in my life. For me, that included forming intimate relationships as well as having trust in myself. Therapy is a great way to get to know yourself and build trust in yourself and your ability to care for your needs.
