I'm a teacher with quiet BPD in my country's second big lockdown.

I am struggling to stay focused on work so much. My symptoms are being exaggerated from staying inside for so long but all my usual coping mechanisms are unavailable right now.
I can't explainy my situation properly to coworkers or friends with out them freaking out.

I lied to my students and told them my WiFi was acting up so I could buy myself some time but now I'm just sat on my kitchen floor ignoring my laptop. 

This is a rant/ request for tips on how to deal with this and keep going.
