People are saying I might have anxiety

So the main reason I've been bearing it more lately is bc lately instead of just occasionally having my arm or hand shake it turned since a few months into shaking and twitching and shit of my arms and legs or my head or sometimes my whole body throughout the day and people say that is a sign of really bad anxiety but idk cause I also have a lot of other mental shit like adhd, autism and cptsd. It also continues after drinking and smoking so it's not bc of addiction
