STRUGGLING with recovery and weight gain and sickness and messiness

I've been sick (with a cold/flu/virus) since Saturday ... i left work early yesterday and have been at home in bed today. I just checked my emails and there is so much work stuff that is stressing me out. I am freaking out as i have a presentation tomorrow in front of a group of PA's/EA's at one of our biggest clients ... i haven't prepared and i hate speaking in front of groups. GOT LOTS GOING ON. and I dunno how to relive stress any other way :S
and my room is a mess cos i've been sick and haven't put my clothes away but i'm too tired to tidy it up.
I've been eating loads and trying to keep pushing through. 
I cancelled my appointment with my psychologist today cos i couldn't face it. :'( 
How do i pull myself together


I AM STRUGLING
