Vicodin helps my anxiety?

Hi everyone, thanx for opening this. I was just curious as to why I feel so great when I take Vicodin. I am so focused and able to write so clearly, i don’t have any pain but when I don’t take it, I feel as though my concentration is spread everywhere equally and I get anxiety confronting or even talking to people. Is there another way with a natural remedy to mirror the effects of Vicodin or will I just have to get used to my anxiety and scatterness? All of the things that are supposed to make me focused like coffee or Adderall make it even worse, so I would really appreciate some help!
thank you in advance!
