I think I'm on the autism spectrum I have many autistic qualities. I don't know how to explain it to my doctor they blame something else.?

I can't keep eye contact, I only allow my family to touch me and I only high five with my feet, I have severe anxiety (I take medicine it doesn't work), I don't get many jokes, I don't understand people's feelings and many times people get mad at me for laughing at times when they are sad, sometimes I just laugh,cry, or break down for no reason I just have to do it, I say random things that people don't understand, I sometimes say things that are obvious and are innaproprate and than get in trouble, I have only one friend who is my dog I can't be friends with humans, I had a difficult time learning how to speak and I stayed in all recess with my teacher who helped me, I am very good at counting, I rock my body and love hammocks, I pop my fingers constantly, I hit my noes to the point of becoming raw, if something is wrong in the store I must correct it or I fell like I'm going to die, I read every sign we pass by our loud, I can not do much my hands are not my friend I can type well thought, I am neat in my own way i have a messy room but I can tell you where anything is at after a month of not being in it. I can't walk and swing my arms like I see other people do I must have crossed arms, I am allergic to meats dairies and gluten, I must have my tv on very loud to hear it and must have captions, I also have twitching blackout moments, I pull my hair out, my doctor says it's from my mom mentally and physically abusing me but that really doesn't bother me any ideas?
