I am sorry to hear of your experience. I too grew up with neglect and have problems with feeling/expressing emotions. I somehow managed to get married to a non abusive man and growing up I was able to 'fake it'. Growing up I copied or mimicked the behavior of others and read books about how to have a conversation with people to make friends. I always however felt like an 'outsider'. It does get better with time and hard work.. for me it has been almost 4 years and I'm now looking for a new therapist that specializes in trauma to go to the next level.
Wishing you lots of healing.
