I haven't felt anything besides low burning self contempt for years. Emotions like sadness and happiness elude me. I haven't sincerely shouted for joy or wept in years. I also have no desire to get close to other people and form relationships. This makes it nigh impossible for me to give a shit about even important things. While I don't feel much pain anymore, I also lack the spark that makes life worth living. I feel like a soulless automaton.
Does this sound like it's related to neurodivergence? I'm 100% depressed, but years of therapy and various different medications haven't done much, so I feel like there must be more to it.
Possibly, it's hard to tell just from that. It could "just" be chronic depression, but there could be comorbid neuro-divergence like autism, or other things like a personality disorder or schizophrenia prodrome. You'd need a psychiatric evaluation to know.
