So, I can never sit still and I'm always moving around or tapping, and sometimes I'll be tapping and shaking my leg ( Ik it sounds weird) and I still feel like I need to move more! But if I don't physically get up and walk I curl up without even thinking about it or trying to do it! It's almost like I'm flinching at something! And it makes me want to cry, I mean I'm not sad, but, it just does. I would appreciate it so much if someone helped me out on why this is happening, thx
