Sorry to hear about your frustrations! I am experiencing a lot of that too with work. I've started a new position, and getting normal tasks done takes forever b/c it's a new system. It can be hard to obtain focus and get prepared. And it stinks knowing that you were the one who could have made this better simply by preparing thoroughly. You have to just get one thing done at a time, one step, one line, one section of your prep. And then start some momentum. I hope this doesn't sound like me telling you what to do... I just hate that feeling too. I've been doing that not eating thing too, but I turned it around this week. I just had too. Not getting enough greens, root veggies, fruits and quality protein alters your mood. Especially when you still are engaged physically.
One task at a time. You will have it knocked out in no time. Good luck on figuring out the work situation.

It is not things that bother us, but the stories we tell ourselves about things.
