I doubt people (many people anyway) are faking. However there are most likely many people who have self diagnosed and are wrong. There is a reason why the DSM has differential diagnosis and why evaluations are more than an online test. There are many similarities between many disorders and while there may be similarities disorders have different treatments, needs, and outlooks. It could be ASD but it could be BPD, Schizoid PD, ADHD, Really bad social anxiety, Depression, Social communication disorder ETC.
I self diagnosed before I was officially diagnosed and so I empathise however I also kept it to myself I knew I met criteria so in my personal life I pushed for a eval it helped of course that many other people has thought the same thing and I was also diagnosed with a ton of things already but made sure to not say anything from the perspective of an autistic person because if I was wrong it could end up harming others with false perceptions. Today things that are kinda normal or slightly odd are seen as signs for autism. Of course not everyone has to be disabled but autism is more complex than what tiktok or instagram says it is. I know the struggle of feeling lost but please just do more research or find a professional if you can.
