I think we all feel lonely and like no one cares sometimes. I haven't been on this site in over a year but what I do remember is that people start to respond and open up more when you make an effort to comment or contribute on posts. It is kind of like getting to know others but in a different way. That way you don't seem like a lurker. Sometimes people look at posts and don't respond because they don't have time or they don't know what to say. Try not to take it too personally. I do not have autism and I frequently feel unable to connect with others and help myself. I think that is called being human.
