I read your post. By parallel, I can go for many hours at a time, regularly, without feeling an emotion. I am just deeply entranced/focused. I would never say this to a NT since this would not really be conceivable to them. But it's still true. Of course, I do not know the ratio of 'feeling' to 'not feeling.' I think feelings are different from emotions, btw. I have some emotions (I think) but they are rudimentary. I think I can name, maybe, 4 emotions that exist for me....unsure. Speculative: 1) Love, 2) Frustrated/Perplexed/Confused (that counts as one emotion for me) 3) Curiousness 4) umm...no word. Maybe delete #4.
Vensin, can you FORCE yourself into just one interest, even if it is not especially compelling initially? By this I mean give yourself an assignment, like homework. Just choose one that seems even remotely interesting. Next, go to an event/exhibit/library, etc where that topic exists. Study. Write, draw. I think this should catalyze an obsession for you! Recall, our kind are inclinded this way - you can do it. Maybe you've just come to a void for unknown reason(s).
An Aspie without an obsessive passion is like a day without orange juice. Did I say that right? Oh, a schedule is immensely helpful or I/you disintegrate. We are marginally cybernetic anyway; I do not see this as a problem. Just don't get rusty.
Induce fun!
