Failed autism test...

But I have major communication problems and when I watch videos of people with autism speaking about their communication problems it hits home with me, a video I watched yesterday even made me realise why I always pull my phone out to play with/look at when I'm speaking in appointments etc. Never understood why I done that but now I realised it kinda helps me speak a little better.

I have no light/sound sensitivity or anything like that, only the communication problems. They say it's down to social anxiety but I'm not sure.

Is it possible to be autistic with only communication problems?

I failed the test and the psychiatrist said it's just anxiety.... but I don't understand how anxiety can cripple your communication skills as badly as mine every day in life
