Do I have symptoms of Asperger's Syndrome?

I've always had difficulties interacting with other people, like classmates, teachers, and extended family members. Although it's easier for me to communicate with my parents, my relationships with them are rocky. When I was in elementary school, I absolutely hated going to the playground or recess, since I would always stay near the walls and watch the other kids play. My teachers always yelled at me to just go and talk to the other kids because they "don't bite." Even if they asked me to play, I would still say no. Speaking to other students in class about anything, like even homework, is difficult for me because I have to prep what I'm going to say to them. I have low self-esteem and hate it when I'm the line leader, since it makes me very paranoid of people behind me. Sometimes, I think people secretly hate me Sure, people know my name in school, and I talk to them during group projects, but I have absolutely no friends. I like to call them my "classmates" not my friends. When I talk to people and we're having a good conversation, which rarely happens, I'm always stuck with a dilemma. I don't want them to leave me, yet I don't want to talk to them anymore. Sometimes I laugh at matters or topics that other people might considered serious or sad, and it confuses me. When someone falls down or cry, I can't help but laugh, even if I don't know all the details. I wish that there was just something, like a mannequin or just somebody's body, that or who I can hug and talk to without them talking back to me, but I don't want a pet. I just don't know how to put it I'm unable to pick up sarcasm in people's voices also. For example, a rather unattractive guy was talking to this girl in my class, and he said that he's good-looking. The girl said, "Yeah, you are." And I was confused because her friends thought that he wasn't and he really isn't. I find it hard to look somebody in the eye when talking to them, so I just look to the left or look down. When I'm sad or disappointed, I usually do a half-smile and open my eyes bigger. Some people say it's weird. I also have bad handwriting (very sloppy and unreadable to most people), and I'm obsessed with certain narrow subjects. Basically, I do try to approach people, yet I have a hard time understanding their actions, speech, and expressions.

With the information you provided, it sounds a little more of the characteristics of Social Anxiety or Social Communication Disorder.
Autism Spectrum Disorders are characterized by these 3 major symptoms
-Inability to or great difficulty socializing and communicating with others
- Sensory sensitivities
- RORR (Repetitive,Obsession, Rituals and Routine)a
- Executive Functioning issues.

you see, many people on the spectrum do not realize they have missed a social cue unless its been pointed out to them, they also do not mis-read body language or facial expressions because they do not pick up on it at all.

people with social anxiety can sometimes forget what to do in a social situation due to the fear and stress.

Do you have any other symptoms other than social?

i apologize in advance if i misread something, i have a poor time reading due to light sensitivity.
