We're the Serlin system, a 15 member mixed origins system (no we do not have DID/OSDD, we're a mixed origins system). We collectively go by they/them pronouns (but individual pronouns depends on the headmate - including leaf/leafs/leafself, star/stars/starself, fae/faer/faerself, and ze/hir).
We like listening to music, playing video games, and researching our special interests (which include mainly religion, history, the occult, spirituality, mad studies, music theory, anti-psychiatry, and/or mycelium/mushrooms). Am also extremely critical of the DSM and ICD - often against them as a practice.
We deal with complex PTSD but not exactly because that's a trauma response not a disorder, and deal with psychosomatic chronic pain due to this. Also deal with intense dysphoria due to withdrawals of psych meds, and we're a psychiatry survivor.
