From what I know the ramble thing, even the inability to relate in a deeper way with others, could it be only (but I’m not diminishing its relevance ok) what I mean that it could be only explained bc of your own psychological issues. I’m not saying this is your case, but people many times put a invisible wall around them to avoid showing up their vulnerability, also, if someone is very focused on something that is causing a suffering, worries...it’s normal that this person doesn’t find easy to connect with others.
I remember that in my first therapy I had to open up myself bc I didn’t let myself take the risk to open to people. My psychologist used to stress on that point.

Said that, I’m not saying you are not right and you can have a little of autism. There’s a whole scale in this condition. However, if I’m not wrong, you can have test done to guess this fact very accurately. At least, you will be sure if you can or not discard that possibility.
In relation to Antisocial traits, I guess you say it bc you don’t feel towards people as you think most of the people feel.
I think the best is to be able to check all these worries with a professional.
Again, I repeat, to sort it out the matter of religious implications, it would be better a therapy online, if you feel confidence enough. Nowadays, with the means that exist, you can follow an online therapy as if you were in the same room with your psychologist.
