Try explaining to your boss, "We need more staff because although I consistently meet all targets I'm just working TOO hard".
I get gas lighted when I do so. They insinuate I'm doing something wrong and need to take more breaks. Uh yeah but then the work doesn't get done, and day by day it builds up, and everyone is clamouring for it, and then you make it seem like I'm at fault again?
I started keeping an Excel spreadsheet of what I do every day just to see how much time I "waste". It turns out I'm doing 6-20 different things a day. Which is what I've been telling them, the load of constantly switching between so many different demands on attention and doing stuff "which should only take a minute" but can turn into hours spread out over days - all the time goes.
I'm extremely sad every day. I'm definitely depressed. But the pay is good and it pays my mortgage. So I feel very trapped.
And yeah when I get home I do nothing. I used to do stuff and blog but now I'm just too tired. All day every day I'm working and making decisions and stressing out - I have no capability to function outside of hours. I can't even make dinner so my partner does it. I find it hard to decide on even simple things and if anything goes wrong I'll break down into tears.
