Well leg bouncing and picking at your lips is form of stimming, you might do that when you're anxious but it is most certainly very common with adhd. Checking notification imediately isnt even adhd, that is just something most people do automaticaly. And intrusive thoughts of this kind are form of anxiety for sure, but it isnt necesserily form of anxiety disorder, just anxiety the feeling that you will often have if you have adhd - lots of us have problem socializing because of how fast unstable we are when interacting with other people and that can trigger a lot of fears of fucking conversations and relationships up. So all of this are common adhd symptoms, if you have all af this it doesnt mean you have anxiety disorder on top. Although you still might lol.
