There’s a lot to unpack there, and I don’t want to appear qualified to help you over this medium. In therapy you could get to the bottom of this, but it takes a lot of work and time. Please have a look into Dialectical behavior therapy, as this seems applicable for the picture you painted about your experience.
Childhood trauma affect people in lots of different ways. Some learn to retreat inward, preferring to live in their own mind over learning to emotionally connect with others. This could look like autism on surface level, however autism doesn’t result from trauma and is accompanied with an array of other signs and behaviours. If you’re still seeing a psychologist, try to work towards opening up your early experiences, especially how you remember your attempts to cope with the world. This is not easy of course but it could help to see yourself as an object of curiosity. Also keep in mind that it is hard to find a therapist who feels right to connect and open up to, even for the average person, so this might be more challenging for you. I hope this helps a bit.
