"find the cause" is exactly what e.g. therapy is for. It's not some insurmountable challenge to do that.

everyone around me who has been starting it is on roughly a ten month waiting list. so they should try nothing until then + several sessions until hopefully figuring something out? some are on their third such cycle because the earlier ones were downright hostile therapists (they're people, just like every profession, they're not all good or effective).
