I know a lot about energy healing and am a big believer in the positive effects IF it is done properly. I had a T try EFT on me once after she had attended a one day workshop on it. I did not find it to be effective but I attribute that to her lack of skill in doing it with me properly. I am sure there are other T's who more successfully integrate EFT into therapy.

I have had other energy healing modalities that have make a huge difference towards helping me process trauma. Just like our bodies hold memories of trauma, so do our energy fields. You've probably heard of the mind-body connection - our energy fields is what makes the connection between mind and body.

Western science does not currently have an effective methodology for testing energy healing quantitatively, nor does the scientific establishment put a priority on funding research in this area. So the fact is that there is simply not enough hard data to disprove the efficacy of energy healing.

As for your T, if you don't want to do it and she still pushes it on you, that seems like a big red flag to me. No matter how effective EFT is, if you aren't willing then you shouldn't be pushed into it.

However, you did say that you haven't been able to access your feelings. You might consider doing some type of energy work outside of therapy (perhaps a qigong class) that will help you move some energetic blocks - that will get your feelings flowing for sure. Once your energy is less stuck, you will be better able to talk during therapy.
