How to know if you’re bad at social cues or autistic?

[Borealis]

I feel that a lot of people seem somewhat hard to predict for me i.e. the way they act towards me is totally unanticipated. For example they randomly get angry and I’m confused as to why and it takes a while for me to process what actually happened, and after a while I may identify some possible reasons why but still not entirely sure.

Are there any legit autists who can tell me if they have the same experience?

[Rædwald]

I think I'm probably autistic, I do this a lot.

Not too sure tbh, I'm good with social cues but naturally a loner. I did some googling and found this, maybe see if your behaviours match - hope it helps.

Social communication challenges
Children and adults with autism have difficulty with verbal and non-verbal communication. For example, they may not understand or appropriately use:
• Spoken language (around a third of people with autism are nonverbal)
• Gestures
• Eye contact
• Facial expressions
• Tone of voice
• Expressions not meant to be taken literally

Additional social challenges can include difficulty with:
• Recognizing emotions and intentions in others
• Recognizing one’s own emotions
• Expressing emotions
• Seeking emotional comfort from others
• Feeling overwhelmed in social situations
• Taking turns in conversation
• Gauging personal space (appropriate distance between people)

Restricted and repetitive behaviors
Restricted and repetitive behaviors vary greatly across the autism spectrum. They can include:
• Repetitive body movements (e.g. rocking, flapping, spinning, running back and forth)
• Repetitive motions with objects (e.g. spinning wheels, shaking sticks, flipping levers)
• Staring at lights or spinning objects
• Ritualistic behaviors (e.g. lining up objects, repeatedly touching objects in a set order)
• Narrow or extreme interests in specific topics
• Need for unvarying routine/resistance to change (e.g. same daily schedule, meal menu, clothes, route to school)
