What would you do, stuck?

I feel like my mental health has taken a very quick nose dive.
There are a few things that have accumulated over the past 2 months, that I think feed into this.
My clinical psychologist told me I need to take a break from work, but I have 4 job interviews, a talk to medical staff to do next week and patient appointments.. it's not the ideal time to just take a break.

I'm literally holding out for next week to be over but I'm not sleeping (2 hours max) and I'm not really eating or engaging well with my work.
I've got days worth of work to catch up on but getting through it all is really hard because everything is taking so much longer to do.
An task that would usually take 1 hour is taking 2 and i can't work any quicker and some of my work can't be passed onto anyone else.

I feel conflicted, but I am not meeting my basic needs so I'm really frustrated that I'm not going to feel better anytime soon until I literally reach breaking point
