I don't go to therapy, but I would say right now you need to focus on getting your ED and SH under control (with CBT/DBT?). That should be your one and ONLY goal and once you make some improvement there, I'd say trying to tackle your complex PTSD with healthy coping skills should probably be your ultimate goal. Though maybe if the PTSD is under control the others may follow but I think the ED is endangering your health tremendously, and you need to make steps towards helping that (big steps!). If your T does not help with EDs, can you at least be referred to a T with some experience helping EDs and SH/SI?
