No it isn't.
Most people with social retardation would take years to learn how to interact with others.
You did it in a year.
That means you have the capability to learn actionable behaviour far quicker than most which is something many people that truly feel the shit your moping about would literally kill for.
Now as the other ausfag trying to help you said,you need to start forcing yourself into temporary social situations to practice the skills you learned.
Things like pubs,bars, casinos.
Anywhere there is a large volume of people that change regularly.Expect.to
fail many interactions for a while, but that's how you.learn.
Knowing what doesn't work is often kuch more useful than knowing what works, because what works can change.
What doesn't work will never work.
