I don't really know if this is anxiety but there are these times where I try and distract myself by being productive, yeah? But somehow, my legs can't stop fidgeting. Like I feel as though I'm bothered or concerned by something unexplainable. After for a while, once I realize it, my heart starts to feel all heavy. I keep trying to distract myself to not mind the current problems I have and to not think too much about it but I can't stop myself from fidgeting. I know it's pretty common (i think) but I usually don't talk a lot about these kinds of worries sooo uhh.. so what do i do?
