Struggling to Connect with People Due to Mental Disorders

A rant just because I don't understand it... I have always been someone who has had attachment issues/difficulty connecting with people, which I recently within the last 2 months discovered is a symptom of a couple mental disorders I have. This symptom appears in my life in a few different ways; I have difficulty with emotionally connecting with people and consistently feel like others don't like me, along with difficulty reading people's body language. I also personally struggle with "if I can't see it, it doesn't exist" which includes items and people. I also am "easily" able to cut people off if they have treated me poorly, meaning that I hardly get an emotional response from people no longer being in my life (it didn't used to be this way). My rant - I have tried to explain this to people, letting them know that I am not trying to hurt them and that I don't do this intentionally, and I've asked people to look into my disorders so that they can understand. But I'm consistently met with responses of "they are people too," "you just need to try harder," and "well if I was you..." It sucks because these responses come from people who are close to me and I don't really know how to respond. It hurts because I want people to understand me and my thought processes but they seem to make judgements based off what I just say, and don't bother looking into the conditions to understand. Does anyone else struggle with this experience?
