autistic

Sorry to type in English but this is the language I feel comfortable with. I am 15 years old, from Tunisia, and I have several problems with my society. My parent (I would rather not tell) refuses to take me for a psychological check. I seek answers for my psychological health. I think I have autism. In fact, I have an excessive fear of others, even my schoolmates. I can not trust people at all, except my parents and some of my relatives. I feel comfortable with my family. Routines and plans mean a lot to me; I put plans to every second in my life. If this plan gets bothered, I feel bad. I often have meltdowns at school, in the classroom, and if I manage to control it, I delay it until I return home. I am interested in collecting Robots and toys. I am obsessed with programming and creating websites. My only friends since my childhood have been robots and mechanical toys. I collect them a lot and spend pretty much money on them. They have even special towels, lives, stories, shampoo... I sleep with them too always. My classmates tell I am too old for that but I cry when they say so. I arrange items in a very special order that often does not make sense to others, but it makes me comfortable. I write books and make music. I only listen to Mozart, Beethoven, Demis Roussos and rarely 80s songs. I concentrate on the instrumental part and get so bothered when I attend parties. I cry when I listen to loud music and immediately have a meltdown. I don't look at others in their eyes. I don't talk at all outside the home. I have no friends because I could not strike any. I get dressed with very old style. I am so sensitive to feedbacks. I was not understood or respected by my peers, but I have a good friendship with my teachers. I have been so different since I was 5 years old. I can not lie, I tell the truth even if it is bad. I often repeat the same thing over and over, until I notice that it was repeated up to 17 times. I am still attached to topics for years. I often prefer to stay alone. The only friends I have are my family, my toys and my computer. I feel happy, sad, mad, anything but it does not show up on my face. I have memories from when I was less than 1year old, very detailed with sounds. I concentrate on the details instead of global things. I collect plants a lot and water them. When they get torn I cry. Even when I talk, I don't know how to express myself; I invent new words, I do the impossible but I don't manage to draw a clear image in the listener's mind. I do not understand what others' plans are, even to guess what the writer of text means from his phrases. I find it easy to imagine a story and create a portrait. I always do things spontaneously and think in a different way. I can not imagine myself being someone else, rather than computer Scientist. Working in groups tires me and keeps me psychologically bothered.
These are my symptoms. Please do I have Autism?
