Don't be scared of failing! Believe in yourself, instil some self confidence, even if it is fake!
Doing ok, had a cappucino this morning and hitting the water now. Got my tetra in a coolbag with an ice pack next to me for lunch later, and hoping to get through 1litre of water before home time. I really struggle with drinking though!
Why don't you have a shake? It might make you feel better.
