Anxiety gives me an abundance of energy, but I've realized that anxious energy is still just energy.  You need to expend it somehow. When I'm talking to people and I'm anxious, I don't try to reason with my head anymore, because I just overthink. I was fighting it "inward" and holding it in. Now instead, I just think about projecting that energy outward somehow. Instead of "how do I stop this" it became "let me use this". When I focus, I focus USING that anxious energy. Sitting in the house all day searching up ways to stop anxiety did not work for me to say the least. It was "inward" and it all went to my head, furthering the issue. Scrolling reddit or my phone all day was basically the same thing. Instead now I always just try to do something, just like cleaning my room or going for a walk. Notice when you talk to athletes or physically fit people, they're usually not stuck in their heard or anxious. Because they're expending their excess energy constantly when they're working out. I just try to not restrict myself.  Sometimes that means naturally letting my foot tap, or just tossing my keys in the air repeatedly lol but hope you get the point. This was probably pretty incoherent, but I hope you can grasp the concept I'm trying to convey. An obviously this is harder said than done and I'm not promoting it as a quick fix.

Tl;dr: Anxious energy is still energy, so just try to express that energy outwards. Both with your body and mind. Try not to hold it in and constrict yourself.
