I've heard many advices from many people to start exercising to fix my anxiety issues. However, i couldn't even get started with my anxiety completely draining me down.

Working from home, i lack the enthusiasm i used to have, and its affecting my work. I get anxious of what my co-workers/supervisor would probably think about my drop in performance. 

After 6pm, I couldn't get myself up and running, thinking about how I've not put in a good day's work. And its becoming a viscous cycle everyday. 

I'm clueless on how to get myself up back again.
