Lost- I work with a lot of people with autism and they have so mcuh to offer the world. Their ideas just need to be expressed differently. Do not think you are worthless, or a sinner or any of that. You will get the help you need a recognie that you are worth a lot, because Hashem put you here. You are a very holy neshama trapped inside a body just like all of us, but you are holier.
Please keep smiling and get yourself some help!
