Autistic people are known to have very few friends and its difficult to make them. But when you get close to the ones you do have and they claim they understand your condition. Do you ask yourself, do they really know? Do they really know what we go through on a daily basis? Do they really know how hard it is to be forthcoming?
Take it from me, I don't have a lot of friends and the ones that I do have I did tell them about my condition. But sometimes I feel that that want to understand and try but they don't know the entire story. I try to let people in and they either accept it or they don't. The ones that do are supportive in their own ways. Sometimes its nurturing and others its not so nurturing. I have the best of both worlds.
One day, you should ask your friends if they truly understand who you are, what you are, and if they can really accept. If they can't cut them out of your life. If they do, you keep them close because that is a true friend.
