Alexithymia is a common companion with being autistic. Sometimes people point out emotions for me that I actually do not have, and I don't like the mental heuristics I have to go through whenever anyone asks me "How are you?" because I don't like following NT protocol, so I do the literal search to see if I'm feeling anything. Most of the time, I don't know what it is. Depression is an overall mood, so I think sadness is happening a lot through my thoughts and lack of inertia, but I don't 'feel' sad all the time, it just is the lack of identifiable emotion.
