Alex, to me as a layperson a lot of these modalities seem complementary. Would it be possibe to pursue some in tandem? For example, writing, EMDR and more traditional talk therapy. A therapist friend of mine is pursuing training in EMDR to supplement his "regular" therapy, not necessarily to be a replacement.
And, since I feel obligated to do it, hopefully in 5-10 years you will be in a position to do an update to this article to include psychedelics (because you will feel confident in the research by then). 😁
