I’ve had similar concerns about myself. I’ve started therapy and found out that I’m suffering from toxic shame - something originating in childhood, developing as you age, and comprehensively modifying behavior in adulthood to include masking, dissociation, lack of emotional connection, inhumanly strong moral guidelines/standards, etc. I’d suggest at least looking up the concept of toxic shame. Also, give yourself some credit and some love; whatever the cause, it’s almost certain that your behavioral patterns were set by forces outside of your control and it sounds like you’ve managed it well
