My body used to do this shiver thing everytime i was having anxiety but it was very rare, like once every 2 months or something. But recently my anxiety and depression have gotten so much worse, and i cannot stop the tics! Especially today its been super bad. And i’ve never had this before. Only those shivers, but now my neck does this twitchy thing, or my whole body will just flinch, and my hands will abruptly move, at some point i couldn’t stop clicking my fingers… i would have never expected that i would develop tics.
