How to stay away from restlessness?

Hi folks. I am in love with IH for the conversations here. I saw a lot of them sharing their opinions. It will be helpful if anyone could share what helped you.

I am getting extremely restless. I am not sure if it's cos I am anxious about too many things at work or thinking more about my future. In between, I did tackle this. But, this seems to be bothering my routine. I don't eat or sleep on time and feel the need to do more and feel I have been lacking behind.
